The basic requirements for drawing network diagrams are

The basic requirements for drawing network diagrams are as follows:

1. The node layout in the network diagram is the arrangement of the nodes in the diagram, which mainly includes hierarchical layout, circular layout, and force direction. Layout and other methods, choosing an appropriate node layout method can make the network diagram clearer and easier to read. According to the scale, density and visualization purpose of the network diagram, select an appropriate node layout algorithm.

2. Adding label information to nodes and edges can further display the specific information of nodes and edges. Labels can include the name, attributes, values, etc. of nodes. Reasonably adding labels to the network diagram can help readers Better understand the meaning of nodes and edges.
