I started writing a new activity graph implementation.
Even though it might be doable to generate the existing graph with large enough hardware, I do not think it should depend on that. Also, I don't want to perpetrate the application sending 30MB of JSON, or whatever it would turn out to be, to the front-end in that web app. Screenshotting it (here) removes that factor but it also removes the interactivity. Here is a unique daily active feeds graph generated from my laptop. The outliers at around two-thirds I think are not correct (I will investigate).

I would like to bill this work to SSB Maintenance (cc @mixmix). The graph seems to be useful thing to the community as a way to see the network activity and growth. I believe reimplementing it as I have started to is appropriate to allow it to continue to work as the network grows.

This was 3.9 hours so far. I estimate another hour for color (color per id as in the original implementation), and a couple more hours for interactivity (hovering over pixels to highlight that id in the rest of the graph).
