Merge in the "gravity" graph Clint uses

It's a cool visualization, but I think it's impeded by needing to query the GH api. Likely useful to instead just use the existing GG cache of issues to populate that chart.

I think the meat of it is here:
https://github.com/crutkas/gravity-func/blob/main/gravity/pages/index.vue

(I'm also under the impression that gravity-func is currently busted, but that can be fixed).

it requires some TLC it works off / on. @dend helped make it.

Happy to help with the application, folks - this was definitely built as an experiment so a lot of the code is not really polished. Let me know if you'd like to set up a call to walk through it and make changes as necessary.
