Engine Metrics

I've setup some metric recording in my engine and game. It aggregates values that I want and saves it out to compact format that I then parse with some Python scripts.

I was thinking about the best way to present this data. I'd like to use a web form if possible, but it seems like that solution is already available. Can anyone recommend any 3rd party web tools that might be useful for rendering that data in a nice way? I have used some python libs for showing graphs, but I would think there are some better things than that.

Thanks for the help!
