Sunburst chart
Sunburst is another hierarchical chart, like the treemap chart, but it is meant to replace pie charts in some situations. Its hierarchical behavior and the ability to show multiple levels of granularity make it well suited for data that has two or more detail levels.
An example is to visualize sales by region broken down into constituent countries. See the following screenshot as an example:
Figure 8.37 – Sunburst chart of sales by country and region
Notice how the regions and countries are not arranged in the same order as in the table; the largest values appear first. It also shows the regional level and then the country level in the same plot.
And that is it for the sunburst chart; we will move on to the next chart.
