Shape a brief the way a studio does. Every space carries a real square footage, so the bubble diagram is area-true (a bubble's drawn area is its area) and the 3D stack has true footprints. Arrange adjacencies per floor in 2D, tilt into an orbitable 3D stacking massing of every floor, and watch a live program table total it — by department, by floor, net → gross by an efficiency factor, and FAR against a site area. An adjacency matrix pins the brief down; departments, units (ft²/m²) and CSV import/export round it out.
Runs entirely in your browser — nothing is uploaded. Build the program by hand or paste a CSV (name, department, floor, area); read it as an area-true bubble diagram, a 3D stack, and an adjacency matrix; export the diagram (SVG/PNG) or the program (CSV).
