/**
 * @class   vtkGeoRandomGraphSource
 * @brief   A geospatial graph with random edges
 *
 *
 * Generates a graph with a specified number of vertices, with the density of
 * edges specified by either an exact number of edges or the probability of
 * an edge.  You may additionally specify whether to begin with a random
 * tree (which enforces graph connectivity).
 *
 * The filter also adds random vertex attributes called latitude and longitude.
 * The latitude is distributed uniformly from -90 to 90, while longitude is
 * distributed uniformly from -180 to 180.
