Here is another script of the day. Today we illustrate the Sunburst visualization. Handy to represent hierarchy. The script visualizes the Pharo collection class library (Array classes vs Set classes vs Hash classes)

b layout sunburstWithRadius: 100.

Here is another script of the day. Today we illustrate the RTLegendBuilder. It is useful to add a legend to a visualization.
