I created one like such:

property_map positionMap; minstd_rand gen; Topology rect_top(gen, -25, -25, 25, 25); random_graph_layout(patentGraph, positionMap, rect_top);

and I get the following errors:

I should have mentioned before that I am using vecS now:

typedef adjacency_list Graph;

You need to use the property map name (not its value type) as the second template argument to property_map. If you are using a bundled property now, the second argument should be "Topology::point_type Vertex::*". You also need to get property_map<...>::type (property_map itself is just a metafunction), and you'll need to initialize positionMap with "get(&Vertex::<member name>, patentGraph)". -- Jeremiah Willcock
