an alternative algorithm for the hierarchical data tree layout, based on phyllotactic patterns in nature, which provide a non-overlapping, optimal packing when the total number of nodes is not known a priori. the word "phyllotaxis" translates to the arrangement of lateral organs on plants. these can be leaves, needles, on a cactus, or seeds on a sunflower. several data visualizations, called "PhylloTrees" show how this algorithm was applied for the layout of large, hierarchical datasets.

Great pictures! Could we have some more details on how they were produced?
