Random Geometric Graphs
rggX is a random geometric graph with 2^X vertices. Each vertex is a random point in the unit square and edges connect vertices whose Euclidean distance is below 0.55 ln n/n. This threshold was choosen in order to ensure that the graph is almost connected.

Graph Files
All files are compressed using bzip2. The number of vertices are all powers of two. The file names are marked by the base-2 logarithm of the graph sizes.
