Chord - source, target, value

viz.ch().source, viz.ch().target, viz.ch().value

These methods can be used to set the accessor functions for the source, target, and values in the data array.

The diagram on the left uses the default accessors d=>d[0], d=>d[1], and d=>d[2] for source, target and value respectively.

The diagram on the right over rides these deafults.
