sdd:size is the size of a sdd:Node, an sdd:vector literal such as "120 56"^^sdd:vector giving width and height.Copy as claim

Unlike most aesthetic quads, sdd:size — like all computed geometry — is materialized unconditionally, whether the layout engine computed it or the author hand-set it (examples decision 6): the SVG projection must be pure arithmetic over the graph, never a layout engine running at render time, so consumers need no layout capability to draw a node's rectangle correctly (spec §5, Tier 1).Copy as claim
