Iroki tree viewer

Hi! I'm the Iroki tree viewer!


Iroki is a super snazzy online tree viewer (phylogenetic or other kinds too!) with automatic customization using metadata or biom files.

You can visualize your newick trees as well as project count data into colors that you can use to style the tree!

If you need to pick colors for your tree, we suggest using one of the lovely palettes included in Iroki!!


If you find Iroki useful in your research, please cite the Iroki manuscript. Thank you!!
