Final answer:
When formatting a pie chart with many categories, removing the legend and using data labels instead can make it easier to interpret.
Step-by-step explanation:
When formatting a pie chart with many categories, it can become visually overwhelming and difficult to interpret. In such cases, it is a good idea to remove the legend and use data labels instead. Data labels can be added to each slice of the pie chart to provide information about each category. This helps the viewer understand the distribution without relying on a cluttered legend.
