Old school D3 from simpler times
A spiral heatmap, showing the number of tourist nights in Berlin (from the Makeover Monday series.
This is based in on the spiral heatmap from this stackoverflow question, for R.
Draws inspiration from Robert Kosara's example, and the research papers linked from that blog posting.
Within the code, you can adjust
- the number arcs per coil (one rotation around the spiral). In this example, it is set to 12, being the number of months
- the radius of the chart
- the size of the hole in the middle
- you can have straight edged arcs, but why would you :)
