GenreMapper is particularly helpful for exploring questions related to the representation of the world in nineteenth-century novels. The visualization currently plots the real-world locations that are referenced in novels from 1800-1900, though this time period could be expanded. GenreMapper indicates the relative frequency with which locations are referenced through a sliding color scale; white equals the lowest frequency, dark red the highest. It also allows users to filter findings based on genre(s), which facilitates analyses of the global scope of individual genres.

Currently, there are 55 novels in the corpus. Future work on this visualization will entail expanding the corpus and adding new features to the visualization, such as a time slider and the ability to filter by specific novels.
