Definition
A Marimekko Chart, also known as a Mekko chart, is a two-dimensional visualization where both the width and height of the bars represent data values. This makes it particularly effective for analyzing market share and segmentation.How It Works
- 1Data is divided into categories and subcategories.
- 2Each category's width reflects its share of the total dataset.
- 3Each subcategory's height within a category represents an additional metric, such as revenue.
- 4The chart provides a comprehensive view of both the relative size and performance of each segment.
Key Characteristics
- Two-Dimensional Data Encoding: Utilizes both width and height to present distinct datasets.
- Segment Comparison: Ideal for comparing segments within a complete dataset.
- Color-Coding: Colors differentiate categories, enhancing readability.
