Artwork that contains organized information for easy reading, identification, and compare/contrast. On Danbooru this usually takes the form of a tabular set of panels (e.g. expression chart), or a line of subjects to be compared visually (e.g. height chart)
Not equivalent to a diagram, which points out or explains the details of something instead of comparing multiple things. For the purposes of Danbooru for numeric data visualized in a spatial manner (e.g. a line chart, scatter plot, bar chart, or pie chart), instead use graph.
