One weighted flow of a sankey, alluvial or chord diagram.
A flow names both of its ends, so the nodes are derived from the edges
and a separate node list would be a second source of truth for something the
data already says -- the treemap's reasoning about paths, applied to a graph.
Their order is first appearance, which is the order the producer drew them.
