This makes me wonder: 1) Does Wikipedia / Wiki* not have a JS pan & zoom tool for graphics like these and 2) Has no one else made something like that just for this graphic?

Asking because the graphical linux genealogy concept / this illustration have been around for a while, as have JS pan & zoom plugins, and it's totally worth having something like this in that format.[1]
