Open your network using Microsoft Excel. Then, as we saw, you need to add a header row which says "Source" and "Target".
Then open your network in gephi:
1- Visualize this network in Gephi using ForceAtlas2, as discussed in the lecture. Display node labels (which are numbers in our datasets, that is, node 1, node 2, etc.).
2- Calculate the average degree”.
3- Perform community structure such that 3 groups are detected.
4- Color-code nodes such that different communities are shown with different colors (there should be 3 colors because there must be 3 communities).
5- Encode node degree in node size, such that nodes with higher degree are shown bigger. It’s your task to determine how it looks “best” such that it is visually discernible which nodes have higher degrees and at the same time the visualization looks “good”.
6- Generate a .pdf output. Make sure the links are shown as straight lines, not curved. Nodes must be depicted as circles.
