Marimekko with normalised rows and columns to show conditional probabilities.
Statistical cousin of marimekko. Used in cross-tabs and contingency analysis where the relative proportion within each group is the point.
When to use
Cross-tabulation where the chart purpose is showing dependence between two categorical variables.
When NOT to use
You just want composition (use marimekko or stacked bars).
