broadcast-graph

Broadcast-graph is a simple graph backend example for broadcast. This backend implements various commands useful for updating directed or undirected weighted edges as well as weighted vertices. Given that this is an example implementation, it uses an ephemeral in-memory store to keep all data (broadcast-stats does the same thing in this particular case).

Commands
