the reset buttons along the left border of the graph view and click to reset
color. Then return to the clique partition list and proceed to group them.
Each node in the simplified graph will now represent a clique. Return to
the reset buttons and reset size to see them all. Next, select them using
the Rectangle Selection tool, and expand them using the context menu.
Expanding will break up the groups into member nodes again, but this time
with convex hulls drawn around each clique. Now that hulls are serving to
cluster nodes, links are adding clutter. Toggle them off at the bottom of the
graph pane.
The last thing that doesn't belong in this picture is the largest group, which
is not actually a clique. Drag a Clique partition type attribute filter into the
Queries pane, and use the context menu to select all groups. Then click to
deselect the null group. Click the Filter button to hide everything but the
true cliques.
Now that fewer elements are visible, you can use the extra space to further
clarify the view. In the Layout tab, choose Force Atlas 2, and select the
Prevent Overlap option before proceeding to run it. Even though links are
not visible, linked nodes will still be drawn together, putting the most
connected nodes in the middle. Use the Ranking tab to increase the size of
nodes until they are touching by mapping degree to a range of 10 to 25.
Expand the controls at the bottom of the graph pane. Map the labels from
the new country column created earlier and make them white. Choose a
condensed font and adjust the scale so that the labels fit snugly within their
circles.
You will immediately note that the dominant country code is US. This is
the Facebook locale that includes English-speaking Canadians, forming the
most obvious group of local fans. Make it a relatively neutral color close to
gray, appropriate for baseline normal, so that other countries are easier to
see.
As shown in
Figure 11-18
, you can now see the 18 most significant cliques
in the sample data. Two clusters of color immediately stand out. One
mysterious cluster of dark gray nodes without country labels is found to the
south, and to the far north a cluster of red nodes with the country code
LT. Smaller clusters of LT exist throughout. LT is the code for Lithuania,
home of starting center Jonas Valanciunas. The Lithuanian clique was one
of two groups you may have noticed being placed most remotely from other
