I'm new to Gephi (and XML, and this sort of network analysis in general). I'm trying to use GeoLayout to plot migration patterns across the U.S. I have an MS Excel file which contains the nodes, edges, the latitude/longitude coordinates of the nodes, and a column containing the edge attributes (which is a number which corresponds to the weighted number of individuals who move from one node to another).
Since the dataset I have is hierarchical-panel data, it is a huge file. Can someone provide some guidance on how to get/import this data into Gephi and use GeoLayout to plot it?
Any assistance is greatly appreciated!
nodedef>name VARCHAR,label VARCHAR, latitude DOUBLE, longitude DOUBLE
edgedef>node1 VARCHAR,node2 VARCHAR, weight DOUBLE
I found that explanation of formatting GDF file *very* helpful, thank you; now, how did you produce the image with the US map behind it? Did you have to export into some kind of KML format and reopen the file or can you create the background map directly in the UI of GePhi?
