# Showcase

The flagship tour of `XWUIChartIsopleth`. Every series is one contour line of equal value sampled across a shared numeric domain, and the showcase walks the four block presets, the sm / md / lg size scale, every display toggle (legend, grid, axis spines, title, grid values, data labels), the stroke and vertex-marker options, the isometric mode with Z stacking, and the loading skeleton.

The final section is a live switcher: one large canvas plus a button per surveyed field that pushes a new iso-line set through `setData()`.
