I was a bit confused to not see that first page simply demonstrate a few examples of charts and that I had to click through each type to get an idea of this library.
I'd suggest pluck out some of the features you find after navigating through to https://chartscss.org/components/ and displaying them on this page so users without a lot of time or patience can quickly look through, maybe copy-paste the code examples to play with it a bit, and get a quick idea of how suitable it is for them.
