Circular packing or circular treemap allows to visualize a hierarchic organization. It is an equivalent of a treemap or a dendrogram, where each node of the tree is represented as a circle and its sub-nodes are represented as circles inside of it.
Here is the
template I start
with when needing to build a circular packing with
one level of hierarchy. Input data is a
.csv
file giving features for each node. Circle
size an color depends on these features. You can
drag circles to reorganize, and hover them for more
information.
