# Showcase

A full tour of `XWUIChartDotDensityMap`: the four block presets, the three block sizes, every grid, axis and label toggle, and palette versus single-token density colour. It closes with pseudo 3D, the loading skeleton, and a real-world population density panel with hover tooltips.

Readings are supplied pre-aggregated, one point per named zone with `y` carrying that zone's count, and the renderer plots the first series.
