ellipse

Plotting coordinates for an ellipse

internal

Generate area-proportional Euler diagrams
using numerical optimization. An Euler diagram is a generalization of a Venn
diagram, relaxing the criterion that all interactions need to be
represented. Diagrams may be fit with ellipses and circles via
a wide range of inputs and can be visualized in numerous ways.
