What type of chart displays aggregations on non-numeric properties?

A listogram is specifically designed to display aggregations of non-numeric properties. This type of chart allows you to represent categorical data, showing how many occurrences of each category exist within a dataset. For instance, if you were analyzing survey results with responses based on different options (like colors, types of pets, etc.), a listogram would effectively illustrate how many respondents chose each category without needing numerical values for the axes.

In contrast, other chart types like histograms focus on numeric data to show frequency distributions, while pie charts represent proportions of a whole, quantifying data that is inherently numerical. A single statistic merely provides one numerical measure and does not visualize aggregations, making it unsuitable for representing multiple categories or groups.
