PhylloTrees - Phyllotactic Patterns for Tree Layout
We explore the use of nature’s phyllotactic patterns to inform the layout of hierarchical data. These naturally occurring patterns provide a non-overlapping, optimal packing when the total number of nodes is not known a priori. PhylloTrees are a family of expandable tree layouts that we developed based on these patterns.
A random balanced tree with 105.100 nodes.
Unbalanced tree showing a weblog file from the University of Maryland.
Unbalanced tree showing 190.000 nodes of the animal kingdom.
This applet shows how to influence a phyllotactic pattern.
