What is a multi-level pie chart?
What is a multi-level pie chart? Multi-level pie charts are a set of concentric rings. The size of each item represents its contribution to the inner parent category. It starts with a single item that is put as a circle in the center. To see the breakup of that item, a concentric ring is set around the central circle.
Which is better pie chart or donut chart?
The pie graph gives a strong and immediate sense of overall proportions, whereas the donut graph leads the reader’s eye around the arcs of the circle – and tend to creates more of a narrative. One advantage of the donut graph is that additional information can be displayed at the graph’s center.
