Since the chart needs to have a hierarchical nature, I think the relationship between category and sub-category is appropriate for this one. As my demonstration, I will be using the Sample – Superstore dataset. In this section, I will be going step-by-step in creating the sunburst chart in Tableau. If you would like to know more about the sunburst chart, check out this page.
It is however necessary to separate the categories with colour.
Even-though this is not a necessary step for sunburst charts, it visually helps separate the differences. In the above example, the shade difference of the outer ring represents the size of the whole for the segments. The parent field will be the closest to the middle while the child fields expand outwards. In the examples case, there is two levels to the hierarchy. Each field in the hierarchy represents a ring in the sunburst chart.
