Sunburst Chart in Tableau

The sunburst chart is ideal for displaying hierarchical data. Each level of the hierarchy is represented by one ring or circle with the innermost circle represents top of the hierarchy. The circle in the center represents the root node, with the hierarchy moving outward from the center. A sunburst chart without any hierarchical data (one level of categories), looks similar to a doughnut chart.


Waffle Chart in Tableau

A waffle chart is basically a square version of a pie chart. Since it does not involve angles, it’s easier for the reader to compare accurately .A waffle chart uses a grid of differently colored squares (hence the name) to show proportion instead of pie slices, making it easier for the viewer to cognitively process the various data relationships. A lot of times, these are used as an alternative to the pie charts. It provides visual communication beyond simple data visualization.


Combine Sets in Tableau

Sets are custom fields that define a subset of data based on some conditions. A set can be based on a computed condition. For example, a set may contain customers with sales over a certain threshold. Computed sets update as your data changes. Alternatively a set can be based on a specific data point in your view. You can use sets to compare and ask questions about a subset of data.
