Places the vertices of a graph in a 2D or 3D grid. add_edges_from([(1,2),(2,5)], weight=2) and hence plotted again. Edges have different colors and alphas (opacity). python3. each edge has a direction associated with it and only one edge between each pair of nodes. You can make customization to the nodes by passing these parameters to the function: node_size, node_color, node_shape, alpha, linewidths. Draw a directed graph using Networkx . The draw() function of networkx library is used to draw the graph G with matplotlib. In the case of a directed graph, it can be generated with DiGraph ().
