Plots of fundamental domains of Gamma_0(N) (and Gamma_1(N))?

[sehlen]

We used to have these nice plots of the fundamental domains (at least of Gamma_0(N)).
We can easily generate them again and I think they should be back in the LMFDB.
When and why was it decided to remove them?

These are back, in the modular curves section.
