// .NAME vtkGeoRandomGraphSource - A geospatial graph with random edges

//
// .SECTION Description
// 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.
