Sunburst Chart

Sunburst charts are used to visualize hierarchical categorical data.

The demo below visualizes the hierarchy of the 27 feelings that derive from the core “happy” emotion:

Pros:

•
The sunburst chart is a great choice to display data hierarchy in a compelling and effective manner.
•
Sunburst charts are both easy to create and understand.
•
The sunburst chart, similar to the pie chart, is a compact shape that makes it an efficient chart ideal for dashboards and/or small screens.

Cons:

•
When sunburst charts are overloaded with datasets, the audience faces challenges to both see and distinguish between the periphery’s arcs.

The sunburst chart can be easily adapted to suit the color-blind community (see below), by adding a monochrome chart with borders.
