Circle Packing
Tableau Viz Extension
A zoomable, nested view of a portfolio: levels of dimensions define the nesting, a measure defines the area, a click dives in.
The whole portfolio in one view
Up to four levels of dimensions nest inside each other, every circle sized by its share. The big players are visibly big, and the long tail is visibly a tail.
Click to dive
A click zooms into a group, the breadcrumb tracks the path, the background climbs back up. The zoom is a reading position: it is never saved into the workbook.
Color that carries a measure
Put a dimension on Color for categorical hues, or a measure for a ramp: profit over a sales-sized packing shows at a glance where size and performance disagree.
