Summary: Depends on D19119. Ref T13083. This is probably still very buggy, but I'm planning to build support tools to make debugging facts easier shortly. This generates a large number of datapoints, at least, and can render some charts which aren't all completely broken in an obvious way. Test Plan: Ran `bin/fact analyze --all`, got some charts with lines that went up and down in the web UI.
