Some ideas of things to do next:
- 
More styles of facets.
 
- 
Implement positioners, especially for stacked and side-by-side bar charts.
 
- 
Keys for aesthetics other than x and y.
 
- 
Size scales for more geometries.
 
- 
Coordinate systems (esp. pie charts)
 
- 
Regularize/rationalize/document use of CSS for controlling appearence.
 
- 
In-browser interactive graphic builder. (REPL?)
 
This project started life as a Hack Week project at Etsy. I’m no longer there but if you want to hack data or something else at Etsy, they’re probably still hiring. See
