Data visualization is the process of translating data findings into a visual context like a map, graph, or chart, so that audience members can easily access the information. This in-demand skill allows audience members to quickly spot patterns, trends, or correlations that have been extracted from large datasets and to use this information to help fuel the organization’s decision-making process. If you’ve always wanted to learn data visualization but can’t figure out how to get started, this guide is for you. Here, you’ll learn more about the various ways to learn data visualization, free resources to take advantage of, and the types of careers that commonly use data visualization.
Data visualization uses graphics like plots, charts, or animations to represent data findings. These visual depictions communicate complicated data relationships in an accessible and engaging format and have a range of applications for sharing data-driven insights with an organization’s internal and external stakeholders. Because an estimated 65% of the population comprises visual learners, data visualization provides a way to quickly and effectively convey data findings. Even though data visualization takes many forms, it shares the common goal of communicating otherwise complex data insights in a memorable and understandable way, even for those who don’t come from a technical background.
Each day, 2.5 quintillion bytes of data are being created, which continues to grow exponentially. This increase in the amount of data has created a corresponding need for visualization practices to share the insights these numbers contain. Data visualization has a variety of uses across industries and professions. It has applications for describing trends or patterns hidden in data and communicating organizational structures or hierarchies. The data visualization process is typically broken into four purposes: to generate ideas, to illustrate concepts, to provide avenues into visual discovery, and to convey data in the form of visualizations.

Those with the skills to create engaging and effective data visualizations have the power to communicate detailed data insights and findings to audience members from all backgrounds. Data visualizations provide a concise and interactive way to depict data trends. Visualizations incorporate color and contrast to present information like sales patterns so that audience members can quickly observe information that may be difficult to see from a graph or spreadsheet. In addition, another benefit of working with data visualizations is that they can provide perspective on the data by placing it in the context of a larger story, which can help audience members understand the information as it relates to an organization’s overall goals or bottom line. Context plays an integral role in helping audiences understand the entirety of the data being depicted, which would be difficult to convey by listing numbers in a table.
Data visualization also provides a better understanding of a business’s operations. Running a business requires staying on top of many moving parts, and data visualizations provide a tool that can depict multifaceted operations and how different business activities connect. Moreover, analyzing and visualizing data provides insights into important business metrics that can lead to smoother daily operations and more successful project execution. For organizations that sell products or services to customers, data visualizations offer crucial insights into customers’ preferences, demographics, and shopping patterns. They provide a way for organizations to use customer-focused data to explore brand perception, customer sentiments, and even what customers post about the product or service on social media outlets. Businesses can then use these insights to tailor marketing strategies and brand outreach.
In addition to providing customer insights and depicting important trends in the data, visualizations also tell a story. Information is presented in an easy-to-understand format, and the audience is taken on a journey that leads to an inevitable, data-driven conclusion. Just like a written story, a visual story has a strong beginning, a basic plot, and an ending that looks into the future, providing recommendations for how to move forward. Instead of requiring tens of thousands of words to tell this story, data visualizations can do so with a series of well-placed infographics, carefully worded labels, and brief descriptions of the content, all of which tell the story of data in the larger context of an organization’s needs and goals.
Data visualization is used across many industries and professions where data is collected. A recent study found that the global data visualization market size, valued at $9 billion in 2021, is expected to expand to nearly $20 billion by 2028. This trend indicates the importance of effective data visualizations and the investment organizations are willing to make to access data-driven insights.
In the transportation sector, data visualization is a powerful tool to help with the task of routing transportation networks like freeways and public transportation. In healthcare, data visualization has a range of applications. It plays an integral role in helping to allocate healthcare professionals and apparatus based on geographical information to ensure patient needs are met. It also helps individuals stay informed about any updates to COVID-19 near them. When used in the public sector, data visualization is used to detect fraudulent activity and improve transparency.
For those who work in the environmental sector, geographic information system models and other data visualization tools aid with action schemes and risk-reduction strategies and also have applications for sustainable environmental ventures and public service initiatives. In addition, the retail industry relies heavily on data visualizations at both the regional and local levels to find ways to reduce operational costs, organize supply chains, and spot instances where costs and profit aren’t in alignment with one another.
Learning to visualize data findings and present them in a way that’s accessible to different audience members is an in-demand skill across industries and professions. We live in an increasingly visual culture, and the human eye is naturally drawn to patterns and colors. Data visualization tools provide a way to engage audience members and communicate an important message at the same time. By seeing information depicted in colorful plots or charts, it’s easy to spout outliers and patterns, as well as to identify trends. This makes it possible for audience members to internalize data findings more easily.
Data visualization is considered to be a form of visual storytelling. It offers an interactive format in which professionals can easily share information, explore opportunities, and examine past patterns or relationships to make educated forecasts about what may transpire. Whether the data visualization is basic or complex, it helps audience members be on the same page regardless of their level of expertise or background working with big data. Because of how widespread data visualization is in every industry, it’s one of the most valuable skills you can have in your professional toolbelt. Those with the ability to tell compelling, engaging data-driven stories with their visualizations have the power to educate and even sway audience members with the insights they find.

The field of data visualization is closely related to data analytics and even overlaps with it in some ways. Generally, data visualization pertains to graphically representing data and information using maps, charts, graphs, and other visual formats. Data analytics is more involved with analyzing large datasets to extract meaningful information. In some ways, data analysis can be considered the first step in the data analytics process, with data visualization playing an important role post-data analysis.
