Waffle Chart
A waffle chart is a data visualization technique used to represent categorical data. It consists of a square grid of cells, with each cell representing a particular category. The cells are filled in proportion to the number or percentage of observations that belong to each category.
Waffle charts are often used as an alternative to pie charts, as they allow for more accurate visual comparisons between categories. In a pie chart, it can be difficult to compare the sizes of slices when there are multiple categories or when the slices are small. Waffle charts also allow for more flexible labeling, as labels can be placed within each cell or outside of the chart.
Waffle charts can be created using various software tools and programming languages, including Excel, R, Python, and JavaScript. There are also online tools and templates available that allow users to create waffle charts quickly and easily, such as Datawrapper, Infogram, and Canva.
