drawgram

Drawgram is a phylogenetic tree visualization and analysis tool developed at the University of Washington's Department of Genome Sciences. It is designed for evolutionary biologists and bioinformaticians who need to draw, edit, and annotate evolutionary trees from sequence data. The application supports importing multiple tree formats, rendering publication-quality diagrams, and adding custom labels, branch lengths, and visual annotations. It is commonly used in academic research for presenting evolutionary relationships and comparative genomics results.
