Figure 15-13:
Expanding a cluster of loans reveals the pattern of activity
for each. Most receive a lump sum and follow a monthly repayment
schedule, with the exception of one, which seems to pay the money back in
a lump sum. Making activity visible makes it easy to spot anomalies.
If you expand the larger cluster of lenders as shown in
Figure 15-14
, you
see that clustering is hierarchical. When the number of accounts exceeds
a manageable number for viewing, it is clustered again. The attributes on
which an account is clustered are configurable. Here, you can see that after
type of account, they are clustered geographically. The first set of lenders
is from the Americas, mostly from the United States, and the next set is
from Europe. The width of the links leading to each indicates the amount of
money flowing to each cluster.
