//! Venn diagrams, as Pele's src/diagrams/venn reads and draws them: a lexer and a parser that
//! make the decisions Mermaid's Jison grammar makes, the db they fill, and a layout that
//! places a circle for each set, with areas in proportion to the sizes of the sets and each
//! pair as far apart as its overlap asks, and writes each region's label and texts where the
//! region has the most room.
