First of all, you need to create a graph. importnetworkxasnxG= nx.Graph() You can use different ways to add nodes. Add one node at a time. Add nodes from any iterable container Add nodes along with node attributes. In this way, you can define many attributes of a node, such as co...
Running the script above using the Conti chat logs yielded a list of 346 unique accounts. This list can then be used to create a graph and show which users sent the most messages. Figure 6. Creating a graph for users with most messages ...
