This map shows the political results of the 2013 Venezuelan local elections (Libertador, in red, for officialism; Chacao, Sucre, Baruta and El Hatillo in blue for the opposition). White represents unpopulated areas, yellow urbanized areas and pink the poorer neighborhoods.
The contour lines shown represent the density functions of the probability that a tweet associated with the officialism or the opposition had been posted by a geolocated user at a given position.
