README.md

Based on the simplest sunburst, but illustrates a time-of-day data pattern. The data.csv file includes:

  • 1 head line: 'time,'
  • 24 hourly lines: '12,time' (hour, hierarchical ref to the head line)
  • 96 quarter-hourly lines: ':00,23,15' (quarter-hour, hierarchical ref to the hour, node size)

(In the .csv, it's tempting to put spaces between lines. Don't do it! It'll keep your d3 from rendering.)

If you're on gist.github.com, you can see me in action at https://bl.ocks.org/denjn5/306b0d38dc0d46be3d83468f369776f4.

We can make this file beautiful and searchable if this error is corrected: It looks like row 2 should actually have 3 columns, instead of 2. in line 1.
