A better pie recipe

Conventional wisdom in infographics has it that pie charts only work with up to six segments and each segment should represent a drastically different percentage. But that doesn't work with the basket of goods in price statistics where you may have to show the percentages of up to 700 items.

The Voronoi Diagram comes to help. Its organic shapes are nested so that even very small shares can be shown. It serves as a special form of a tree map. The statistical use case is aptly named Price Kaleidoscope, also a better marketing term that doesn't involve cooking.

Here is a beautiful showcase of Scalable Vector Graphics at work. Read more about Voronoi diagram - a new visualisation tool for the price statistics or visit the SVGopen conference.
