putting 1 Picture box on the form and write this code also you can change the the minus number beside of Width and Height to get best result System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath(); gp.AddEllipse(0, 0, pictureBox1.Width – 3, pictureBox1.Height – 3); Region rg = new Region(gp); pictureBox1.Region = rg;
In fact, the original visualization is a prime example of one method to show multiple links between nodes, that is – using arcs rather than direct paths, so you can see both incoming and outgoing links. This concept can be extended to show multiple of each of these types of links by changing the radius … Read more
An improvement to the reply above is adding the connectionstyle to nx.draw, this allows to see two parallel lines in the plot: import networkx as nx import matplotlib.pyplot as plt G = nx.DiGraph() #or G = nx.MultiDiGraph() G.add_node(‘A’) G.add_node(‘B’) G.add_edge(‘A’, ‘B’, length = 2) G.add_edge(‘B’, ‘A’, length = 3) pos = nx.spring_layout(G) nx.draw(G, pos, with_labels=True, … Read more
You will find http://graphdrawing.org/ and this tutorial, by Roberto Tamassia, professor at Brown University, quite helpful. I like a lot Force-Directed Techniques (pp. 66-72 in the tutorial) like the Spring Embedder. You assume there is a spring or other force between any two adjacent nodes and let nature (simulation) do the work 🙂
