TreeView X is an open source and multi-platform program to display phylogenetic trees.
It can read and display NEXUS and Newick format tree files (such as those output by PAUP*, ClustalX, TREE-PUZZLE, and other programs). It allows users to order the branches of the trees, and to export the trees in SVG format.
It uses the wxWidgets C++ library.
