geom_node_tile | R Documentation |
A treemap is a space filling layout that recursively divides a rectangle to
the children of the node. Often only the leaf nodes are drawn as nodes higher
up in the hierarchy would obscure what is below. geom_treemap
is a
shorthand for geom_node_treemap
as node is implicit in the case of
treemap drawing
