Add graphs to keep track of relative position over time

[NickNiebling]

I love this project and it gives a good indication of the current relative performance AND efficiency between languages 🥇

To make it even more useful, this project could show the relative position on graphs over time (I assume this can be extracted from readme history), as I assume there is a development over time, which could also more clearly show who is more invested and actively pursue improvements continuously 💯
