Thanks to open data, I offer the same node hierarchy of OTT, among 10 other backbones, but present it with 3 different (perhaps less dazzling) viewing mechanics switchable at the top: Icicle, which packs hierarchy into a fixed vertical height while allowing depth to stay horizontally reachable. Chronogram is the opposite, showing structure even 10 levels deep in a compact horizontal region, but at the expense of large vertical expansion. And Tree, the default, which is a compromise that can also show multiple winding paths simultaneously by folding them against the gutter.
I also focus less on the tree itself and more on trait overlay and rolling up thousands or even millions of species into compact segments so you can get a feel for how many chordates lay eggs or how many spiders are carnivorous at a glance. https://ptree.org/#OTT
