|
||
|
|
* @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.
