Introduction
Visualization is an essential part of front-end development. There are many solutions to build these charts. However, I can argue that the D3 library is the best solution for achieving such tasks. When building simple line chart to complex charts like a racing bar chart, D3 have you sorted.
They say "Never as a butcher, if meat is tender", and as a D3 enthusiast, I can be biased on the topic. However, if you give me a few minutes I can persuade you on this one.
Data visualization with D3
The Internet has grown to be the most powerful tool for sharing information. All professionals have embraced this tool as a means to communicate with their clients and other stakeholders.
An economist can share their economic growth or inflation rate trend charts and journalists get to communicate the spread of a disease in a given geographic location through an interactive map. As a developer, when I am met with these scenarios, D3 js is always my tool of choice.
