Phylo.io

Phylogenetic trees are pervasively used to depict evolutionary relationships.
Increasingly, researchers need to visualize large trees and compare multiple
large trees inferred for the same set of taxa (reflecting uncertainty in the tree
inference or genuine discordance among the loci analyzed). Existing tree
visualization tools are however not well suited to these tasks. In particular,
side-by-side comparison of trees can prove challenging beyond a few dozen taxa.
Here, we introduce Phylo.io, a web application to visualize and compare
phylogenetic trees side-by-side. Its distinctive features are: highlighting of
similarities and differences between two trees, automatic identification of the
best matching rooting and leaf order, scalability to large trees, high usability,
multiplatform support via standard HTML5 implementation, and possibility to store
and share visualizations. The tool can be freely accessed at http://phylo.io and
can easily be embedded in other web servers. The code for the associated
JavaScript library is available at https://github.com/DessimozLab/phylo-io under
an MIT open source license.
