Dendrogram of the clustered context factors. This tree diagram is read from left to right; every factor is one cluster at the beginning. Similar clusters are linked step-wise (vertical lines).

The longer the horizontal lines and leaps become, the bigger the dissimilarity becomes, which is where to stop the agglomeration.
