Sunburst Chart in Tableau for Hierarchical Data
This is another blog in the series of Advanced and Interactive Visualization using Tableau, that can add an edge to your Tableau skills and help create an impact in the presentation Reports and Dashboards.
This is about — Creating a Sunburst Chart for dosplaying Hierarchical data.
Sunburst Charts basically belong to a family of Pie Charts.
Here, each level of the hierarchy is represented by one ring or circle with the innermost circle as the top of the hierarchy. A sunburst chart without any hierarchical data (one level of categories), looks similar to a doughnut chart.
Hence, it can be created as similar to a Doughnut chart in Tableau, that is by using Dual Axis in 2 pie charts.
But this technique doesn’t give you the flexibility to work on multiple levels of hierarchy, and is mostly limited to 2 levels.
Below picture gives an idea of Sunburst chart with Dual Axis (on the Left) and the Sunburst Chart with the 2nd technique (on the Right).
