交互式操作进化树

1年以前，实现了ggtree交互式操作方法identify，当时写的博文，为此专门录了视频。如果要做演示的话，交互式还是挺好的。

We are happy to announce that ggtree supports interactive tree annotation/manipulation by implementing an identify method. Users can click on a node to highlight a clade, to label or rotate it etc.

Here is an example of highlighting clades using geom_hilight with identify:

Here is another example of using emojifont to label clades.

Interactive tree manipulation, e.g. rotating clades, is also possible.
