Data visualization: What it is and how to tell stories with data

What is data visualization?

Data visualization is the process of presenting information in graphical or visual form to facilitate understanding, analysis, and communication of patterns, trends, and relationships that exist between data. It is a powerful tool for communicating information effectively, helping users to gain a deeper and more meaningful understanding of the data. When faced with large amounts of complex data, visualization allows us to transform that data into clear and meaningful visual representations.

Data visualization helps turn all that detailed data into information that is easily understood, visually appealing, and useful. It identifies patterns, trends, and relationships that may go unnoticed in a list of numbers or a table of data. Providing raw numbers and figures can help support better organizational decisions through tables, charts, graphs, diagrams, spreadsheets, maps, and numbers.

In addition to facilitating understanding, data visualization also improves the communication of information. By presenting data in a visually appealing and organized way, visualizations help to capture the audience’s attention and convey the message effectively. By simplifying complex concepts, highlighting relevant information, and making it easier to compare and interpret data.

What does it mean to tell stories with data?

Data-driven storytelling is about crafting an engaging narrative based on complex data and analysis that helps your story and influences and informs a particular audience.

Data-driven stories use various types of data, including scatter plots, geographic maps, time scales, line graphs, pie charts, bar charts, heat maps, and tree graphs.

Creating a data-driven story can have a positive impact on individuals and the organization. Some of the benefits of telling a successful data story include:

  • Add value to data and insights.
  • They allow you to interpret complex information and highlight key points that are essential to your audience.
  • Helps give a human touch to your data.
  • Offer value to your audience and your industry.



How are data visualization and data storytelling similar?

Data-driven stories and data visualizations work together with the same goal in mind: To create an engaging, factual, and contextual narrative. They are not interchangeable, but two sides of the same coin. Visualization provides the proof your narrative needs, while storytelling presents all your information as logical and coherent.

Using data visualization to improve storytelling

Data visualization can be a powerful tool for improving stories, as it can help support and communicate the message more clearly and effectively. When using data visualization to enhance stories, it is important to consider the following:

  1. Identify key data: Before starting to visualize data, it is important to identify the key data that is relevant to the story you want to tell. This may involve collecting and organizing the data in an accessible and understandable format.
  2. Select the right type of visualization: It is important to select the type of data visualization that is most effective in communicating the message. Examples of visualization types include bar charts, line graphs, maps, and flow charts, among others.
  3. Keep it simple: Often, less is more in data visualization. It is important to avoid information overload and keep the visualization simple so that the data is easily understandable.
  4. Tell a story: Data visualization is a tool to tell a story, not an end in itself. It is important to use data visualization to support and enhance the story, not simply present data for its own sake.

Make sure that telling a data-driven story adds value

It is important to make sure that telling a data-driven story provides value and is relevant to the target audience. To achieve this, it is important to follow these steps:

  1. Know your audience: It is important to know your target audience.
    Understand their needs, interests and desires, and create a story that fits their expectations and preferences.
  2. Identify the key message: Before you start telling a story, it is important to identify the key message you want to convey. This message should be clear, relevant and meaningful to the audience.
  3. Verify the accuracy of the data: Before using data in a story: it is important to verify its accuracy and reliability. It is important to ensure that the data is accurate and up to date, and that reliable and verifiable sources are used.
  4. Use data visualization to improve the story: As mentioned above, data visualization can be a powerful tool for improving stories. By using data visualization, information can be communicated more clearly and effectively, which can enhance the user experience and add value to the story.
  5. Evaluate the impact of the story: After the story has been told, it is important to evaluate its impact and determine whether it has fulfilled its purpose. This may involve measuring user engagement, assessing audience feedback, and comparing the results with the intended objectives.



Data-driven stories are transforming the way people consume information

There is the potential for data-driven storytelling to vastly change the way we consume data and analytics.

Data storytelling brings a human touch to the sometimes indecipherable numbers and figures presented to us by raw data. Crafting a narrative is an important part of the process, but creating a strong story depends on your ability to understand and translate that information with impartiality.

This means analyzing and exploring the data from different perspectives and identifying patterns, trends, and relationships that can help build a coherent story. By understanding data objectively, you can communicate more effectively and avoid misinterpretations.

Microsoft Power BI can be an effective tool to help you tell that story. It allows you to visualize, explore and share data. You can transform complex data into graphs, charts, tables, and other elements that help tell your story and convey the desired message clearly and effectively.

In conclusion, data storytelling can change the way we consume information and analytics. By giving data a human touch, data-driven stories allow us to better understand information, make more informed decisions, and communicate messages effectively.
