//! XY charts, as Pele's src/diagrams/xychart reads and draws them: a lexer and a parser that
//! agree with Mermaid's xychart.jison, the XyChartDb they fill, and a layout of the axes, the
//! bars and lines of each series, and a legend.
//!
//! Values are numbers as JavaScript's are, f64, as Number reads them from the text.
