# Showcase

A full tour of `XWUIChartDayHourHeatmap`, the day by hour activity grid where cell opacity encodes the value. The sections cover the 7 by 7 week board, how the number of cells reshapes the grid, the four block presets, the three sizes, cell value labels, hover interactivity, the pseudo-3D transform and the loading skeleton.

Every instance mounts into its own child div because an XWUI component clears the container it is given, and all styling comes from theme tokens so the page reads correctly in light and dark themes.
