The declaration variants an amCharts series can back.
The union is smaller than MaidrTraceDeclaration because a declaration is
still a claim about a drawing: there is no amCharts construct behind a
hexbin, and a block declaring one is reported rather than read into a
layer with nothing in it.
choropleth is here for the ordinary reason and alluvial for a strange
one. An am5map.MapPolygonSeries bound to a valueField is already read as
a map with no declaration at all; declaring one says which of the author's
own columns carries the region, the value or the centroid pair, for a map
that hangs them somewhere amCharts was never told about.
alluvial is the odd member. Every other entry names a reading amCharts
draws with a series class worn by something else; an alluvial has no class
of its own at all, because it IS an am5flow.Sankey — the same weighted
flow, drawn with the nodes repeated across stages rather than budgeted left
to right. So the drawing cannot separate the two and the author has to, and
the declaration carries nothing but which of the two it is: the nodes, the
links and their weights are already in the chart.
