The C3 Charting library is one of the best libraries out there for charting. It gives us control over almost every pixel of the graph. We can update bar colors, text size, date and number formatting. There’s so much to customize.

This library is powerful, but it is simple to set up. It taps into the powerful but confusing D3 JS library.

It has 8.6K stars on and is used by 3.9K users. It is well known.

We use this library all the time. Check it out.
