igraph – The network analysis package. igraph is a collection of network analysis tools with the emphasis on efficiency, portability and ease of use. igraph is open source and free. igraph can be programmed in R, Python, Mathematica and C/C. Plot symbols and colours can be specified as vectors, to allow individual specification for each point. R uses recycling of vectors in this situation to determine the attributes for each point, i.e. if the length of the vector is less than the number of points, the vector is repeated.

A graph database is based on graph theory, uses nodes, properties, and edges and provides index-free adjacency. These database uses graph structures with nodes, edges, and properties to represent and store data. Every element contains a direct pointer to its adjacent elements and no index lookups are necessary in a graph database.
