# ggtree: a phylogenetic tree viewer for different types of tree annotations <!--[](https://travis-ci.org/GuangchuangYu/ggtree) [](https://ci.appveyor.com/project/GuangchuangYu/ggtree/branch/master)--> [](http://www.bioconductor.org/packages/devel/bioc/html/ggtree.html#archives) [](http://bioconductor.org/checkResults/devel/bioc-LATEST/ggtree/) [](http://www.bioconductor.org/packages/devel/bioc/html/ggtree.html#since) [](https://support.bioconductor.org/t/ggtree/) [](http://www.bioconductor.org/packages/devel/bioc/html/ggtree.html#svn_source) [](http://bioconductor.org/packages/stats/bioc/ggtree.html) The `ggtree` package extending the `ggplot2` package. It based on grammar of graphics and takes all the good parts of `ggplot2`. `ggtree` is designed for not only viewing phylogenetic tree but also displaying annotation data in the tree.
