Documenting the colours and shape is fastidious and it doesn't travel with the diagram, a legend does.
A legend is just an item with a format and description of the format as the item label.
With nomnoml we can't choose the order of nodes, but maybe we can put all legends in a transparent box, or maybe it will just position single elements nicely.
A possible hack would be to link invisibly legend element so they'd be on an horizontal line
