First, here is what you do with the raw network.
In the NodeXL ribbon go to Analysis -> Groups -> Group by Connected Component. This populates the Groups worksheet with all the disconnected groups of nodes.
Then, decide on one to focus on. G1 should be the largest and most interesting, but this isn't always the case. You can calculate Group Metrics in the ribbon Analysis -> Graph Metrics to give you more information about each group to choose one you care about.
In the Groups worksheet, select all the groups you want to remove (e.g., all but G1). Then change to the Vertices worksheet. In the ribbon select Visual Properties -> Visibility -> Skip. This skips all the vertices in those groups for all computations, layouts, and visualizations.
Now you can go ahead and run CNM or any other grouping algorithm on the remaining connected network to create the FD-GIB layout like your example.
