What is the method to create an exploding pie chart in Excel?

Creating an exploding pie chart in Excel involves emphasizing specific slices of the pie to highlight them visually. The correct method is to click on a singular slice of the pie chart and then drag it outward. This action effectively 'explodes' that slice away from the rest of the pie, thereby creating a clear distinction and helping to draw attention to the particular data represented by that slice.

This method is widely used because it allows for a straightforward visual representation where users can interactively manipulate the chart to enhance clarity and focus on particular data points without affecting the overall integrity of the chart. When slices are separated in this way, it enhances the chart's readability and visual appeal, making it easier to understand the comparison between sections of the data.

The other options do not accurately represent the action needed to create an exploding effect. For example, there's no direct "explosion" function available from the chart interface, and adjustments to data labels or attempting to explode the whole chart do not yield the desired effect. Therefore, dragging a singular slice is the correct and most effective method to achieve this visual modification in an Excel pie chart.
