How can a pie chart be customized?

Customizing a pie chart primarily involves enhancing its visual representation and improving its readability. Modifying colors allows you to differentiate segments clearly, which is crucial for interpreting the data at a glance. Adding labels provides context for each segment, helping viewers understand the precise values or categories represented in the pie chart. This type of customization makes the chart more informative and tailored to the audience's needs.

While changing the chart type entirely might be useful in some cases, it would no longer qualify as a pie chart. Adjusting the overall size is not comprehensive enough to really customize the chart meaningfully. Removing all outlines might affect the aesthetics but would not contribute positively to the understanding of the data presented. Thus, the most effective and relevant methods for customization revolve around modifying colors and adding labels.
