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.
