h_chord_graph()

		const uint	rwidth = 10 )

A chord diagram, flattened into a linear horizontal form.

Rendering set/subset of metadata with "playing" compound grammars.

The Vertical (roughly, in thirds): top is actual age graph middle is ages plotted on horizontal axes bottom is playing age graph, inverted.

And then a connecting line will be drawn from the actual age to the playing age.

The Horizontal: Use linear scaling for age values, instead of bell shaped scaling for glyph. have 10 values (00-09, ..., 90-99) + 100+ + unknown +ambiguous -> 13.

Process cumulative age values 1-3.

1. ages vo map
2. ages playing map
3. largest count value over all of the age values

Process cumulative age values 4.

1. coalesce/flatten multi-playing values "50-59 playing 50-59, 60-69" "50-59 playing 10-19, 60-69 to "50-59 playing 50-59" x 1 "50-59 playing 10-19" x 1 "50-59 playing 60-69" x 2
