coef.euler

Returns the <code>$shapes</code> data frame: a tagged uniform schema with one row
per set, a <code>type</code> column, and shape-specific columns
(<code>h, k, a, b, phi, width, height, side</code>) populated according to the
chosen shape (other columns are <code>NA</code>). For circle/ellipse fits the
legacy <code>$ellipses</code> slot is still populated for back-compat; consumers
that need the new shapes (rectangle, square) must read <code>$shapes</code>.

internal

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