820 dots, one per employee. A unit layout is a plain function of every mark and the plot rect, returning positions, so a shape can be registered from outside the library. Every shape below comes from apexcharts/unit-shapes; the last row are strokes, where the dots pack a thickened line rather than an outline, which is how a shape with no interior joins in. Switch views: the same dots flow into the next arrangement, keeping their identity, colour and size, rather than the chart being torn down and rebuilt.
Same data, same dots. Only the position provider changes.
