Treemap, sunburst, and circle chart are used to visualize hierarchy.
Treemap is used to visualize hierarchy.
The following demo visualizes the size of the Canadian provinces and territories, where the regions are on the top, and the provinces or the territories are under. The drill down feature allows users to discover in depth each region by clicking on it.
The elements of each group are hidden under the group name to improve clarity and minimize distractions.
Sunburst is used to visualize hierarchy.
As the groups and their elements are always visible, try to avoid confusing viewers by keeping the number of groups and elements low.
