not exactly the stuff you are looking for . but it is something like that

I don't think there's a single cohesive timeline out there that treats all super hero comics as a whole and is interesting to look at.

One tip might be to google the publishers and see whether there's something on wikipedia or something.

Marvel and DC are the biggest ones when it comes to superheroes.
