**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.
