# Showcase

A full tour of `XWUIChartCosine`: semidiurnal tide heights from two ports, read as the periodic cosine curves they are, with both series sharing one Y domain. The sections walk the four block variants, the three sizes, stroke weight, dash patterns, endpoint arrows and marker styles, then the furniture toggles (grid, grid values, axis spines, legend, data labels), hover interactivity, the pseudo-3D transform and the loading skeleton.

Every chart mounts into its own freshly created host element, because an XWUI component clears the container it is given.
