Plan

First priorities:

build out the structure module, which should generate node-edge data structure from input JSON
- create toGraphViz method
- create fromGraphViz method: look at perfopticon? (see how they did it)
- create node builder, edgebuilder, and navbuilder (and wrap all 3 into 1)
- add example with set diagram

Build UI tool for creating DN strcture visually
Models to help with UI tool?
Keyboard instructions
Build examples:
- Visualizations:
  - Maps/spatial
  - Graphs/diagrams
  - Sankey/alluvial/flow
  - Math functions
  - Super cool custom work
- Non-visualizations:
  - Simple game UI in canvas or webGL
  - Simple Doc UI in canvas or webGL
  - ??
- Patterns:
  - Serial (bar)
  - Simple Nested (scatter aka vega-lite example we currently have)
  - Grouped (bar/line)
  - Binned (histogram/continuous scale line/scatter)
  - Multi-tree (existing example with highcharts)
  - ??
- Input modalities
  - Screen reader/keyboard
  - Voice
  - Hand gesture
  - touch (and mobile screen reader)
  - Click + focus handling (with on-demand rendering?)
Run user studies on previous examples
- Put user study results on the webpage itself perhaps?
