I am using an adjacency matrix to create a network of 56 people. I have manually modified the graph because I wanted certain groups of people to appear next to each other, etc.
Now, there have been some minor changes in my excel file and I would like to avoid having to create a whole new network graph which I would have to modify again. So, what I am looking for is a way of updating the data set on which the graph relies but I couldn't find any such command.
Can you help?
