When to use a donut chart

[Ehsanuls55]

Donut charts are a great visualization tool, but they aren't always the best fit for every data visualization. Knowing when to use one can help make your data clearer and more engaging.

Below are some scenarios where a donut chart is the best way to represent data:

Comparing parts to a whole
Donut charts show how different parts contribute to a complete data set.

Example

If the market share of several companies is shown, each donut segment represents the share of one company. The canadian cto cio email list chart makes clear the space each competitor occupies in the market without overwhelming the viewer with numbers.

This visual comparison helps the audience quickly understand proportions.

Highlight key categories
A drill-down donut chart is especially effective for highlighting specific data points .

Example

Let's say you're presenting company expenses and you want to draw attention to marketing costs. By slightly "exploding" the marketing segment outside of the donut, you can visually highlight it, making sure that viewers notice it immediately.

It is especially useful in presentations where specific data points need to be highlighted without getting lost.
