What is Data Storytelling?

Data storytelling is a powerful tool that transforms complex data into compelling narratives, making insights more accessible and engaging. By leveraging data visualization, graphs, and infographics, data storytelling helps organizations present data-driven evidence in a way that drives meaningful decision-making and influences stakeholders effectively. This article delves into the significance of data storytelling, highlighting its components, benefits, and best practices. We will explore how data storytelling can enhance business intelligence, facilitate better data analysis, and empower individuals to make informed decisions through visually captivating presentations and dashboards.So in this article we basically talking about the storytelling through data and how with the help of data analysis storytelling you can do it.

What is Data Storytelling?

Data storytelling communicates insights and information derived from data through compelling narratives, visuals, and data-driven evidence. It involves presenting data to make it easier for people to understand, engage with, and draw meaningful conclusions from the information presented. By weaving data into a cohesive and persuasive story, data storytelling enables organizations and individuals to make informed decisions, influence stakeholders, and create impactful presentations.

Why Do We Need Data Storytelling?

The art of Data storytelling is simple and complex at the same time. Stories provoke thought and bring out insights that could not have been understood or explained. However, it’s often overlooked in data-driven operations because we believe it’s trivial. We fail to understand that the best stories not presented well are useless!

In several firms, the first step towards analyzing anything is storyboarding. Questions like why do we have to analyze it? What decisions can we make out of it? Sometimes, data alone tells such visual and intricate stories that we don’t need to run complex correlations to confirm it.

The best example of needing stories and visuals to explain data is Anscombe’s Quartet. Anscombe’s Quartet is a set of four datasets with very similar statistical summaries but completely different when visualizing them.

These are the four datasets used to depict the Anscombe’s Quartet. If we look at mere numbers, we find that their summary statistics are almost identical.

Let’s see how they appear when we visualize them.

Did you ever think these four quartets would have such varying visuals?

How Data Storytelling Works?

Data storytelling is the art of turning raw data into a compelling narrative that is easy to understand and meaningful. It combines data analysis, visualization, and storytelling techniques to communicate insights effectively. Here’s how it works:

1. Start with a Clear Goal
   • Identify the purpose of your story. Are you trying to inform, persuade, or inspire action?
   • Define the key message you want your audience to take away.
2. Collect and Analyze Data
   • Gather relevant data from reliable sources.
   • Analyze the data to find patterns, trends, or insights that support your message.
3. Create a Narrative Structure
   • Build a story with a beginning, middle, and end.
   • Start by setting the context (why this data matters), present the insights (what the data shows), and end with a conclusion or call to action.
4. Use Visuals to Simplify Complexity
   • Turn data into charts, graphs, or infographics to make it easier to understand.
   • Choose visuals that align with your message and help highlight key points.
5. Add Context and Emotion
   • Explain the significance of the data in simple terms.
   • Use relatable examples or real-life scenarios to connect with your audience emotionally.
6. Keep It Simple and Focused
   • Avoid overwhelming your audience with too much data or technical jargon.
   • Focus on the most important insights and present them clearly.
7. End with a Call to Action
   • Encourage your audience to take the next step, whether it’s making a decision, changing behavior, or exploring the data further.

Three Components of Data Storytelling

• Data: This is the information we collect and analyze. It could be numbers, words, pictures, or other things we gather to learn.
• Story: This is like a tale we tell using the data. We organize the data to make sense and tell a story with a beginning, middle, and end. It’s like explaining why the data is important or interesting.
• Visualization: This means turning the data into pictures or graphs. Instead of just looking at numbers, we make charts or diagrams to help people understand the information better. It’s like painting a picture with the data.

Benefits of Data Storytelling

1. Data storytelling makes complex data more accessible and understandable, allowing audiences to grasp insights easily.
2. Engaging narratives and compelling visuals keep audiences hooked, increasing retention and attention.
3. Storytelling with data empowers better decision-making by presenting evidence-based insights.
4. Stories are memorable; data combined with storytelling creates a lasting impact on the audience.
5. Convincing narratives backed by data builds trust and influences stakeholders effectively.
6. Data storytelling adds a human touch, making data relatable and emotionally compelling.
7. Data-driven stories create empathy, helping organizations connect with customers’ needs and experiences.
8. Storytelling reveals trends and patterns hidden within data, leading to valuable discoveries.
9. Data stories help identify and address challenges, promoting innovative problem-solving.
10. Storytelling unifies teams around data, enabling better collaboration and shared vision.
11. Data storytelling is a potent tool for advocating social causes and driving positive change.
12. Organizations that excel in data storytelling gain a competitive edge in their industries.

How to Create Data Stories?

To create a story or a plot is the first step to selling your ideas with a strong foot forward. Most people fail to think their stories through and cannot differentiate themselves from mediocrity. Let me take an example and guide you through creating stories.

We will explore a dataset with news headlines and details of every stock price from the NASDAQ 100 tech companies. The columns selected are as follows:

Begin With a Pen-paper Approach

Visually engaging presentations will inspire your audience, but they need more work. Some of the best presentations have been created on rough pages and tissue papers. Scripting down your ideas and flow before structuring your story is essential to your final product. The most important thing you can do to improve your analytics is to have a story to tell. A flow you can generate can have a lot of friction in your end result.

Aristotle’s classic five-point plan that helps deliver strong impacts is:

1. Deliver a story or statement that arouses the audience’s interest.
2. Pose a problem or question that has to be solved or answered.
3. Offer a solution to the problem you raised.
4. Describe specific benefits of adopting the course of action outlined in your solution.
5. State a call to action.

I structured my report by involving plots that would help me better understand my data. My first idea was to use the data I had to make better business decisions about stocks.

A line graph would help me analyze trend lines of specific stock prices.

As I can see, all stocks dropped in February 2016. Scraping news articles only from that period would help me identify what caused the drop. Now, how do I select which news source to scrape from?

By identifying which news source reported most about a particular stock, we would have reason to believe that this source is a good source for that stock.

Dig Deeper to Identify the Sole Purpose of Your Story

• Identify closely the idea of your story. Ask yourself, “What am I giving with this story?” It’s never the story alone but what the story can do to improve decision-making. What you’re displaying is the idea of better decision-making or analytics.
• Develop a personal “passion statement.” In one sentence, tell your prospects and why you are genuinely excited about working with them. Your passion statement will be remembered long.

Use Powerful Headings

• Create your heading and a one-sentence statement for your story, visual, or analysis. The most effective headlines are concise, specific, and offer a personal benefit.
• Remember, your heading is a statement that offers your audience a vision of a better understanding. It’s not about you. It’s about them.

Design a Road-Map

• Create a list of all the key points you want your audience to know about your story, visual, or analysis.
• Categorize the list until you have only three major message points. This group of three will provide the verbal road map for your story.
• Add supporting evidence to enhance the narrative under each of your three key messages. This could include personal stories, facts, examples, analogies, etc.

Conclude with Brevity

Now that you have presented your story’s points, your conclusion should be short and powerful. In my report, I mentioned small 3-4 line summaries to conclude why to buy a particular stock.

Data Storytelling During Predictive Modeling?

We are often questioned about how our stories and visuals can work or help when it’s time to create mathematical models. During all stages of predictive modeling, storytelling could be a vital addition to your analysis.

Let’s understand the basic steps involved in creating models from our data and then tell stories within them.

Data Exploration

The first step of model building is understanding your data. I’ll show you instances and how to explore your data without computing complex statistics.

Let’s consider a dataset on Wine Quality. This is the structure of the dataset is as follows

Here, we can see the associated summary statistics of the dataset.

So, if we need to see whether there is any correlation between alcohol volumes and wine qualities, how do we do it?

We could either compute Pearson’s ‘r.’ It would help us build a model but would not help us analyze much.

This shows a very strong correlation between Alcohol content and wine quality. But does it tell you anything else?

Ideally, it doesn’t. So, what does?

Let’s see how we can visualize these and tell much more about them.

First, we’ll see how Wine Quality relates to Alcohol content.

Here, we can see that the higher alcohol volumes relate to better wine qualities, which helps us better understand our data and spot outliers in this scenario.

Next, would you wonder how acid contents in your wine affect its quality?

This would be one way to visualize the effects of acid. As the Violin Plot expands horizontally, it shows that there are higher numbers of data points within those areas.

Feature Visualizing

After you generate features, how do you see how well one is predicting?

Graphs tell us how far away our predicted points are from our fitted line.

Another example where we might have to visualize newly created visuals is the Principal Component Analysis. If you want to get an in-depth understanding of PCA, you can go through this article.

This is the Iris dataset found in RStudio.

We find these statistics when we run the principal component analysis on this dataset.

However, plotting this, we find that the resulting visual is much more informative than the statistics.

Model Creation and Comparison

Coming to the model creation phase, we usually find the need to understand how our data is being fitted.

This is a model that predicts whether the car should go fast or slow based on the grade of the road and bumpiness.

As you can see, the decision boundary classifies most of the data, but an accuracy of 88.21% doesn’t tell much of a story. Here, we can even see how far the misclassified points are from the decision boundary.

We can also compare certain algorithms and techniques by examining their decision boundaries, as we did above.

Another example using the Iris dataset is shown below.

There’s little information here to derive valuable insights about our model.

On the other hand, this plot shows a clear classification boundary where the Species separate.

Best Practices for Data Storytelling

Now that you know the scenarios where we can use story telling to explain our point, I will give you a few practical tips when you take this up on your own.

• Always label your axes and give the heading of your plot.
• Use legends where necessary.
• Use colors that are lighter on the eye and in proportion.
• Avoid adding unnecessary details, such as backgrounds or themes, to your visualization, making it difficult to read.
• Only a point can simultaneously encode two quantitative values based on a horizontal and vertical location.
• Never use points for visualization if you are doing time series encoding.

Using Data Visualization to Enhance Your Data Storytelling

Data visualization is a powerful tool to enhance data storytelling by making complex data more accessible, understandable, and engaging. Here are key strategies for using data visualization to elevate your data storytelling, along with examples:

Strategies for Using Data Visualization in Data Storytelling

• Choosing the Right Visualization Tools: Microsoft Power BI and Tableau offer robust features for creating dynamic and interactive visualizations. These tools help present data in a way that is not only visually appealing but also informative. Using these platforms, data analysts can create dashboards that provide a comprehensive data view, facilitating better understanding and analysis.
• Utilizing Templates and Best Practices: Leveraging pre-designed templates can save time and ensure consistency in your visual storytelling. Templates also help maintain a professional look, ensuring that your visualizations meet industry standards and effectively convey the intended message.
• Integrating Real-Time Data: Incorporating real-time data into your visualizations ensures that the information presented is current and relevant. This approach benefits marketing campaigns and social media analytics, where timely data is crucial for tracking and optimizing performance.

Conclusion

In an era where data drives decision-making, data storytelling is indispensable for translating complex information into actionable insights. Using advanced data visualization tools like Power BI and Tableau, data analysts and scientists can create interactive dashboards and compelling narratives that resonate with stakeholders. Effective data storytelling not only simplifies data complexities but also builds trust drives change and enhances the impact of marketing campaigns.
