In the principles of proper visualization, there is a rule to use only a few marks on the chart. Instead, you can use the grouping method according to any logic. But what if you need to display the members of the group in some way? Use the tooltip!
In our example, we will show the top 5 sub-categories by sales and group the remaining sub-categories into the value Others. A list of sub-categories that still need to enter the top 5 and their sales will be displayed by hovering over the Others mark.
