PhyloGrapher helps you visualize and study evolutionary relationships within families of homologous genes or proteins (elements). It is a drawing tool that generates custom graphs for the given set of elements. It can be used to visualize any type of interactions between elements you want. Each gene or protein on a graph is represented as a colored node (vertex) and connected to other nodes (vertices) by lines (edges) of variable thickness and color based on the similarity of genes or proteins (distance matrix). The user positions these nodes in such a way as to optimize visualization of the inter-relationships between the nodes. Unlike classical phylogenetic trees, the physical distances on the graph between nodes have no information content. The level of similarity between genes or proteins on PhyloGrapher's graphs is indicated by color and line thickness.
