I have provided a picture of the example I am trying to understand. I have looked everywhere for information about the subject (books, youtube, scholar articles, google).

I understand that a sparse graph representation has non-zero values entities but other than that I have no idea how get from the adjacency matrix to sparse graph.

If anyone can provide a reference or explain it will be greatly appreciated.

Sorry but I could not rotate image. You can just download image and rotate it in your image viewer.
