I run a coding boot camp and one of the final projects this cohort is doing data visualization. We're using UT99 logs to do this visualization. We're doing parsing of logs generated by the utstats bot, then toss those into reports. I wanted to show some images and see what people a) thought of the images and b) thought might be interesting data to show, either per match or as aggregate data.
Currently we're only doing standard death match. These graphs are being displayed during a convention to get people's attention while they walk around the show floor and convince them to jump in and play some matches of UT.
And now, a few screen shots:

This first one is to play around with the style of the graphs, and see if we could replicate the feel of UT99.

This is a chord graph, showing kills vs deaths by weapon. It still needs some coloration to make it more readable, but I thought it was pretty sweet looking.

This is a heat map of kills over time. This lets you see if you are a steady player or go through slow/fast periods while you play.
Mostly we're looking for feedback on what players think of the graphs or what other graphs people might like to see. Once this is done, we'll push out all of the code so everyone can see it. It's using Node on the back end, D3 on the front end and a document database to store the data (CosmosDB to be exact).
