//! Pie charts, as Pele's src/diagrams/pie reads and draws them: a tokenizer and a parser that
//! read what Mermaid's Langium grammar reads, the model of their tree, and a layout of the
//! slices, their percentages and a legend.
//!
//! Values are numbers as JavaScript's are, f64, as a value may be written with more digits
//! than any f64 holds.
