A mosaic chart uses variable-width and variable-height tiles to represent two categorical dimensions and their relative magnitude at once. It is a powerful way to visualize the joint distribution of two categorical variables.
This sample displays 1,000 iconic music recordings broken down by decade (1910s–2000s) and lyrical theme—Heartbreak, Love, Party Songs, Politics & Protest, and more. A union tooltip mode is enabled so hovering over any decade reveals all topic counts simultaneously.
Follow the step-by-step Mosaic Chart Tutorial to learn how such charts are built. See the Marimekko Chart documentation for all configuration options.
