# Showcase

The flagship XWUIChartVenn demo. It shows two, three and four overlapping sets, the sm/md/lg sizes, how the y value drives each circle radius, the block and chrome options (legend, title, value callouts), and an interactive audience overlap beside the loading skeleton.

Each set is one point of the first series: the name comes from `label` (falling back to `x`) and `y` sizes the circle.
