Visualization is a process of plotting and drawing various kinds of charts and graphs for the given data to make it more understandable, since, a picture worth a thousand words. Charts and Graphs are one of the major components in an application. Many real-world apps like StackOverflow and GitHub use Graphs and Charts in a large number of use cases. Looking at raw data can be really frustrating and people tend to lose interest very easily. So, the use of pictures, graphs, and charts in applications can give very good insights into the data.
Flutter offers a large number of options to work with charts and graphs. One can create some very great user experiences with Graphs and Charts using Flutter. Flutter contains a package named charts_flutter which gives a very vast and elegant toolkit for working with charts and graphs.
