A mosaic chart uses variable-width and variable-height tiles to reveal the joint distribution of two categorical dimensions. It is particularly useful for spotting patterns in survey and self-assessment data.
This sample maps five core skills—Business, ML/Big Data, Math/OR, Programming, and Statistics—across four data-profession personas: Data Businessperson, Data Creative, Data Developer, and Data Researcher. The X axis is oriented on top for easier category reading, and a union tooltip lets users compare all skill weights for a given role in one hover.
Follow the step-by-step Mosaic Chart Tutorial to learn how such charts are built. See the Marimekko Chart documentation for all configuration options.
