## Thanks: Jul for the idea to add a datestring. See:

## Thanks: @gffhcks for noting that inf() and debug() should be swapped,
##         and that critical() used $2 instead of $1

Demonstration of an ArcDiagram layout function with both distance-based and compact level modes. The compact mode works better for orthogonal edges, and can use much less vertical space. The distance mode works better for curved arc edges.

The alice.json dataset is the first line from Lewis Carroll's Alice in Wonderland, parsed with the Stanford Parser.
