Hi, 1) Graph Builder 1.0 supports directed graphs only where we call the incident edges as inEdge and outgoing edges as outEdge. For example, in the picture below, Edge1 is outEdge for vertex Alice and inEdge for vertex Bob [cid:image002.png@01CF5898.CEA225C0] 2) Graph Builder does not provide visualization, but you can use the partitioned graph format in tools like GraphViz [http://www.graphviz.org/] and Gephi [https://gephi.org/] Thanks, -Kushal. From: GraphBuilder [mailto:graphbuilder-bounces@lists.01.org] On Behalf Of ?? Sent: Saturday, April 12, 2014 8:53 AM To: GraphBuilder Subject: [GraphBuilder] (no subject) Dear all, I am a beginner of Graphbuilder. I use the first vision of the graphbuilder. There are two sub-folders in the "graph_partitioned" folder of the output, i.e., the "edge" and the "vrecord" subfolder. We need helps regarding the following two aspects: (1) Could anyone please help us clarify the actural meaning of the elements "inEdge" and "outEdge" in graph_partitioned\edges\partition0\subpart0\edgelist? (2) Could you please let us know whether Graphbuilder provides the visualization of the constructed graphs, or could you please give us some suggestion on graph visualization tools for integration? Your kind help and valued time are highly appreciated. Thanks and best regards,
