PlotPanel looks quite nice for a launch, congrats! (Graphy looks decent too) For those who work with Python it is hard to beat plotly.js for front end because it transfers almost directly to whatever plots you are doing in your notebooks. Extremely customizable and also powerful. Well one downside to Plotly is that it is quite heavy about 3-4MB. Couldn't figure out a way to separate different graph types.
