Phylograph is an application that reads trees up to 1000-1200 leaves and constructs and edits graph drawings in different layouts. Phylograph roots the tree using as outgroup a single leave or a whole branch, simply via the computer mouse. The tool incorporates a wide set of functions to expand, compress, invert, and/or rotate a tree. Phylograph allows the cutting of branches and the incorporation of decorations such as tags, brackets, boxes, and arrows.
The tool also allows the user to save the tree drawing as a re-editable project and offers the choice of various exportable image formats, including a HTML format suited to databases. Phylograph is a Java application. This means that the tool runs on personal computers as a standalone program. We also present here an overview of the algorithms used by Phylograph to represent the tree drawings.
In the upcoming weeks we will update and upload more content to this manual.
