Marginal Distribution Maps are a technique that incorporates rug plots in maps. The rug plots provide reference points along the axes of the map. The technique is not new but the novel term ‘Marginal Distribution Map’ has been proposed here. The Marginal Distribution Maps have been used here to visualise polygonal housing data, for example, at borough-level.

The Marginal Distribution Map is used to visualise the spatial extent of sites less than 0.25 hectares in area in the London Borough of Haringey. The spatial data is polygonal and the rug plots provide reference points.



The Marginal Distribution Map is applied here to land use data less than 0.25 hectares in area in the London Borough of Merton.
