A mosaic chart (also called a mosaic plot) uses variable-sized tiles to display the joint distribution of two categorical variables. It is well suited for tracking how demographic segments evolve over time.
This sample visualizes Pew Research Center data on social media adoption in the United States from 2006 to 2021, segmented by four age groups (18–29, 30–49, 50–64, and 65+). It applies the "pastel" theme, point padding, percentage-formatted HTML labels, a styled HTML title with subtitle, and rich HTML tooltips that describe adoption rates in a readable sentence.
