Hi Everyone,
I'm a mathematician/coder/visualization person living in San Francisco.
I've been in contact with Karsten Loesing about making more interactive graphs for the tor metrics website. I've made some progress which can be viewed here:
http://tigerpa.ws/tor_metrics/
You can select a region in the bottom graph to set the time domain of the top graph. You can click on the buttons on the right to add lines to the graph.
It's still a work in progress, so there are still bugs and I've open to suggestions on making it better. Currently it only shows graphs for network/relays data. I'm planning on adding the ability to view graphs for all the other data on the current tor metrics site.
The code lives here: https://github.com/tigerpaws/tor_metrics
Thanks, Walter
