Data is becoming more and more important every day. For any organization, data plays a big role in making important decisions. Data analysts and researchers may gather important and useful information, but it won’t help if clients and users can’t understand it. That’s why data visualization is so important. It is based on the idea that “a picture is worth a thousand words.” This means turning complicated data into simple and clear pictures that make it easier to understand.

In this article, we’ll learn about data visualization, what are data visualization tools and explore best data visualization tools. We’ll also discuss some benefits of data visualization.

What is Data Visualization?

Data visualization means showing information and mainly numerical data in a visual and easy-to-understand way using images. Some common visual formats include charts and graphs like pie charts, bar charts, line graphs, area charts, cone charts, pyramid charts, donut charts, histograms, spectrograms, cohort charts, waterfall charts, funnel charts, and bullet graphs. It also includes diagrams, plots such as scatter plots, distribution plots, and box-and-whisker plots, as well as different types of maps like symbol maps, choropleth maps, isopleth maps, and heat maps. Other visuals like figures, correlation charts, and percentage meters are also used. Often, these visuals are combined into one view called a dashboard.
