Data labels

Data points can be easily annotated with labels to help improve the readability of data.


Legends provide additional information helpful in identifying root nodes in a sunburst chart. They can be docked to the left, right, top, or bottom positions around the chart area. By clicking a legend item, we can toggle segment visibility or highlight the segment.
