Org Chart (Radial -> Dendrogram Transition)
license: gpl-3.0
height: 950
border: no

Forked from Mike Bostock's dendrogram example, with a couple modifications:

  • Transition between cartesian and radial charts
  • slightly diff data file, classic employee model
  • straight line from node out
    • nvm, doesn't work with transition
  • legend, colors
