Proportional area chart
This is a chart where the areas of geometric shapes, symbols or icons represent values. The bigger the symbol, the greater the value it represents. This is good for comparing values and showing proportions because it gives a quick view of the relative sizes in the data without using a scale.
Use simple shapes such as circles and squares that are easy to compare visually, or symbols that are easily recognisable and relevant to your data. Make sure that the scaling of your symbols is consistent and easy to interpret, and label each shape with its value. Don't use if your data has negative values or if the differences in values are too small to be seen easily from the sizes. Don't use if you want to accurately show values — this chart is typically used for presentational purposes rather than for analysis.
