Which type of visualization allows you to show a third dimension of data?

The bubble chart is particularly effective for displaying a third dimension of data in visualizations. In this chart type, two dimensions are typically represented by the X and Y axes, while the size of the bubbles in the chart corresponds to the third dimension, which can be a quantitative value. This allows for an additional layer of information to be conveyed alongside the standard two-dimensional representation, making it easier for viewers to interpret complex datasets.

The other chart types, such as the scatter chart, primarily focus on representing relationships between two numerical variables, without incorporating a third dimension effectively. Pie charts represent data in a circular format, illustrating parts of a whole but do not accommodate a third data dimension. Area charts track changes over time for one or two dimensions but likewise do not effectively represent a third axis in the same way that bubble charts do.
