NESTED PIE CHARTS IN TABLEAU

Pie charts are one of most commonly used charts for data visualization, primarily because they are as easy to create as they are to understand.Here,the independent variables are plotted in clockwise or anticlockwise direction on the circular graph.Radial lines are used to connect the arcs to the center of the circle, thus dividing the pie into slices. Before we move on to talk more about the pie chart and the kind of data that can be plotted and analyzed using the pie chart, we’ll see a simple example for this chart. The idea of this nested Pie chart/ Donut plot with subgroups visualization came from this stackflow post .

This donut chart is essentially a two Pie Chart stacked on top of each other with an area of the center cut out.

STEP 1: DATA PREPARATION

Good data preparation allows for efficient analysis, limits errors and inaccuracies that can occur to data during processing and it is essential as a prerequisite to put data in context in order to create any out of box Charts.
