Inspired by a Tableau Workout Wednesday from last year, we are going to make a Marimekko chart. A Marimekko chart, also known as a Mekko chart or mosaic plot, is used to visualize categorical data across two variables. Both axes use a percentage scale that determines the width or height of a bar. Think of a Marrimeko chart as a combination of a 100% stacked column chart and a 100% stacked bar chart. These charts are often used to provide a picture of an industry or customer base by segment.
This is a lesser used chart type because it's really only appropriate to provide an overview. It's difficult to compare segments when they do no share a common baseline.
Our Marrimeko chart is visualizing the percent of women in different job levels. The height of each segment of a column is determined by the percent of that job level that correspond to the selected gender. The width of the column represents the percent of jobs that are categorized as the selected job level. Since we have grouped gender into women and other, and placed the women category (which is the focus) at the bottom, this chart doesn't suffer from some of the design and analysis limitations mentioned above.
