15.5. IMPORTING/EXPORTING NETWORK DATA 319JessJoshJillJeffJohnJaneJackFigure 15.9: Visual output of Code 15.16.One useful feature of read_edgelist is that it can import not only edges but also theirproperties, such as:Code 15.18:John Jane {’weight’: 0.8}John Jack {’weight’: 0.8, ’trust’: 1.5}Jess Josh {’weight’: 0.2}Jess Jill {’trust’: 2.0}Jack Jane {’weight’: 1.0}The third column of this data file is structured as a Python dictionary, which will be importedas the property of the edge.Exercise 15.12 Create a data file of the social network you created in Exercise15.7 using a spreadsheet application, and then read the file and visualize it usingNetworkX. You can use either the adjacency list format or the edge list format.Exercise 15.13 Import network data of your choice from Mark Newman’s NetworkData website: http://www-personal.umich.edu/~mejn/netdata/ The dataon this website are all in GML format, so you need to figure out how to import theminto NetworkX. Then visualize the imported network.
