Events everywhere

Scroll when the mouse is over the graph to travel through time!

This spawned from the need to write a nomination for the Technology Society for overall best society of the year (of which we came top 5!) where we had to describe the kind of things that we got up to. There was a need for a way to quickly show the diverse range of 87 events we ran over the academic year, so the idea was that it'll be nice to quickly scroll through them, including data about interest and participation which we got from Facebook events. (This reveals some planning 'oops' moments when events on the same day overlaps!)
