\caption{Compiled-scene review using original simulated data and artwork. (a) A smooth response curve and a second supplied response. (b) A seeded point cloud. (c) Supplied category values. (d) A vector-hatched section cropped by a painted window. (e) A simple processing diagram. (f) A shaded native 3D solid. The paint revision changes only the cloud colour; the data revision changes only the category values. Axes, text, curves, clipping and compositing use the same compiled scene for SVG, PDF and PNG. Revision counters describe rendering compilation, separately from document layout and export. No measured data or statistical inference is represented. MIT, Mark Marosi.}
