Proportional area chart square
This is a chart where the areas of squares represent values. The bigger the square, 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.
Make sure that the scaling of your squares is consistent and easy to interpret, and label each square 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. And don't use if you want to accurately show values — this chart is typically used for presentational purposes rather than for analysis.
