Render metrics using the plot.ly javascript framework
This is the first working version with some config but still needs a lot of work to to feel ready for prime time. In particular it currently assumes the first three values it gets are x, y, anx z. They must all be the same size and we assume they are on the same point.
- First working version
- Better metric resolution
- Map metric names to x,y (z), color, and text
- Support plotly timeseries
- load plotly.js from CDN?
