In this recipe, we'll need the ggraph and igraph packages and dependencies, including magrittr, readr, and dplyr. We'll need the bio-DM-LC.edges file from the datasets/ch7 folder of this book repository. This is a file that contains some gene functional associations from WormNet. The network contains ~1,100 edges and ~650 nodes. You can read more about the data here: http://networkrepository.com/bio-DM-LC.php.
