What is the fastest way to add a lot of nodes/edges to a NetworkX graph programmatically?

Question

I need to quickly create a large NetworkX Graph, with data coming from a query against some database, returning a lot of data. I gear adding nodes and edges one by one would be ridiculously slow. Is there a faster way?

Answer 1

To add edges, use Graph.add_edges_from.

To add nodes, use Graph.add_nodes_from.
