London Bus Spider Map

I wrote this web app one weekend to answer two simple questions that I often ask myself about unfamiliar parts of London:

1. Where's the nearest bus stop?
2. Where do the buses go to from there?

Here's a live demo. You'll need to zoom in a bit for bus stops to start showing up. Pick one, and it'll draw a geographical map of the bus routes to and from that stop.

Source code can be found on GitHub.

Transport for London's own website does have something sort-of similar, but it doesn't colour-code or label routes, and it suffers from excruciating performance issues.
