"WebThe biggest difference between NetworkX and cuGraph is with how Graph objects are built. NetworkX, for the most part, stores graph data in a dictionary. That structure allows easy insertion of new records. Consider the following code for building a NetworkX Graph: # Read the node data df = pd.read_csv( data_file) # Construct graph from edge list.
