Drawing a network diagram
There are many situations that require drawing connections between people or objects. A connected graph occurs when every vertex of the graph is accessible from every other vertex. An Isomorphic graph occurs when two graphs have the same number of edges and vertices and all corresponding vertices have the same degree and the edges connect to the same vertices. This post will go through drawing network diagrams in QCE General Maths.
How to draw a connected graph
The following video explains how to draw a connected graph.
How to draw isomorphic graphs
The following videos explain how to draw isomorphic graphs and examples further explaining the concepts.
Drawing a network graph to represent a map
Often, network graphs are used to represent a map of a town or country. The following video will show you how to solve a practical example.
Drawing a network graph to represent a table
Sometimes, we are given tables and told to draw a graph based on information in a table. The following video will illustrate how to do this.
