What aspect does NOT fall under the category of map layout elements?

The aspect that does not fall under the category of map layout elements is color intensity. Map layout elements are the components that are typically included to enhance the map's readability and provide essential context to the viewer. This includes elements like the title, which informs the audience about the map’s subject; the north arrow, which indicates the orientation of the map, and sources of data, which credit the origin of the information depicted on the map.

Color intensity, while important in the visualization of data (for instance, representing density or magnitude visually), is a characteristic of the data representation rather than a layout element itself. Layout elements aid in the map’s overall presentation and help users to interpret and understand the map effectively, whereas color intensity serves primarily as a visual cue within the graphic representation of the data depicted.
