In eulerr: Area-Proportional Euler and Venn Diagrams with Ellipses

Per-shape bounding box dispatch. Reads the type tag on shapes (rows are assumed to share a tag since a diagram fixes one shape kind), then picks the appropriate width/height calculation. Falls back to the rotated-ellipse formula when the type is unknown so external callers constructing ad-hoc ⁠$shapes⁠ frames still get a sensible box.

Description

Per-shape bounding box dispatch. Reads the type tag on shapes (rows are assumed to share a tag since a diagram fixes one shape kind), then picks the appropriate width/height calculation. Falls back to the rotated-ellipse formula when the type is unknown so external callers constructing ad-hoc ⁠$shapes⁠ frames still get a sensible box.

Usage
