[graph-tool] Query regarding graph layout in graph-tool

Hi All, I am very new to graph-tool and looking into its documentation. I've been playing with the F-R algorithm with weighted edges to layout time series data. I want to know is it possible in graph-tool to nominate a node to be the centre of the graph and have the layout chose the distance of near by nodes to be directly proportional to the strength of the edge weight. The more two nodes correlate, the closer together they are. Any help is appreciated. Thanks, Kapil PS: If graph-tool is not yet capable of nominating/fixing a particular node, is there any other python graph package which can do so? -- Kapil Gupta Phone: +91-9312505395 Alt Email: kapilgupta.iit@gmail.com
