Ptree — Interactive Tree of Life

Ptree is the new work of Michael Dayah, creator of Ptable (the periodic-table site used in classrooms for decades): the whole tree of life as an interactive web page — click to expand branches, filter by dozens of traits (body size, lifespan, habitat…), and switch between tree, branch and trait-column views, all driven by open databases like GBIF and NCBI. For front-end folks the reason to keep it is the interaction itself: expanding, filtering and view-switching across massive hierarchical data stays silky-smooth — a rare benchmark for interactive data visualization.

1. Browse it as a design reference: feel how deep-hierarchy expand/collapse and view switching stay smooth.
2. Click a species node to see how trait columns and ecological relations (predation/symbiosis/pollination) are presented.
3. Compare with the author's earlier Ptable to see one person's decade of evolution in interaction thinking.

• Silky expand/collapse across the entire tree of life
• Dozens of trait filters with multiple views
• Powered by open science data (GBIF, NCBI and more)
• Built by the creator of Ptable, deep interaction craft
