Equal angle layout
==================

This example showcases the "equal angle" layout. This layout is inspired by the `ggtree <https://yulab-smu.top/treedata-book/chapter4.html>`_ layout with the same name, which originally comes from Joseph Felsenstein's book "Inferring Phylogenies".

The "equal daylight" layout is an adjustment of the equal angle layout that attempts to spread out leaves more evenly
for imbalanced trees. ``iplotx`` has an experimental implementation of this layout.

.. warning:: "Experimental" means you can use it but the API and resulting layout may change in future releases.
