Stats Visualization for eg profile readme?

Hello,
According to [1] it is possible to make nice profile READMEs, and the one shown on that page has nicely visualized stats (weekly coding stats for various languages).

I’d like the same, but can’t figure out how this was done.
Is there something like [2] for gitea (not as far as I could find) ?
