Part-to-Whole Composition Mechanics

A Marimekko chart (also known as a Mekko chart or market map) is a two-dimensional stacked bar chart where both the width of the columns and the height of the segments within those columns represent quantitative data. The column width typically illustrates a total group volume (such as total market size), while the height of each segment represents its percentage share within that group (such as a company’s market share). This dual-axis scaling creates a composite view of category proportions and absolute scale simultaneously. All chart rendering processes locally on your device, guaranteeing that your data remains private and is never uploaded to external servers.
