node 0 [898]
| node 1 [560]
| | node 2 [49]
| | | node 3 [3]
| | | | leaf 4 [1]

The number between "node/leaf" and the brackets is the cluster number.
E.g., for the node "node 1 [560]", this is "1" and for "leaf 4 [1]"
this is "4".
The number in the brackets denotes the number of instances in the
node. E.g., the leaf "leaf 4 [1]" contains on a single instance, but
"node 1 [560]" contains 560.
