[tor-relays] new tor network graphs on OrNetStats

Hi,

up until now OrNetStats mainly consisted of tables with lots of numbers about tor network stats that can be interactively searched, but graphs are usually a lot easier to comprehend, that is why I'll be adding more graphs to OrNetStats.

Today I've added the first new graph on the main page that shows the 10 largest proven exit operator domains and their exit fraction in a bar chart: https://nusenu.github.io/OrNetStats/index.html

In the long run I plan to publish (and re-implement) all graphs that currently are nonpublic (and not on OrNetStats yet). This should give more people a better view / understanding about what is happening/changing on the tor network infrastructure.

kind regards, nusenu
