Module figures 

Figure-level builders: charts that own their own axes / multi-panel layout and render onto a whole DrawingArea, rather than plugging into a single draw_series call.

• CorrelationHeatmap — labeled correlation matrix + colorbar.
• MissingnessHeatmap — data-quality present/absent map for EDA.
• PairPlot — scatterplot matrix with distribution diagonals.

Modules

colorbar

A vertical colorbar drawn directly onto a drawing area, shared by the heatmap figures.

correlation_heatmap

Correlation-matrix heatmap figure: labeled grid + colorbar, rendered onto a drawing area.

missingness_heatmap

Missingness heatmap figure: a present/absent map across observations (rows) and variables (columns), for EDA data-quality checks. Column labels carry the per-variable missing percentage.

pair_plot

Pair plot (scatterplot matrix): every variable against every other, with a distribution view on the diagonal. Renders onto a drawing area by splitting it into an n×n grid and reusing this crate’s series plus plain plotters scatter marks.
