**Quadrant Charts** are a [[Diagram Types (index)|Visual Analysis Technique]] for plotting entities[^1] across 2 [[Dimensions]] simultaneously. They are very common and used to depict all sorts of things. See the [[#Examples]] below. The strength of quad charts is their ability to [[Information Mapping|map]] an arbitrary number of items across 2 dimensions while maintaining [[Simplicity]] and, perhaps, the [[Optimum Level of Information]].
Quadrant charts are the most _common_ form of matrix diagrams, but there is no real limit to the number of categories laid out about the horizontal and vertical axes. See the [[#Risk Matrix]] below. You don't actually even _need_ sections representing categories, you could simply have the two axes without stratification. See
# Examples
