Example view of the TreeGraph 2 GUI showing taxon counts displayed as branch widths. The taxon counts of all terminal nodes have been imported from a table (text file) to a hidden node data column. The imported annotations have then been used as source data to set the terminal branch widths. For each TreeGraph 2 document, one can optionally view the node/branch data table in the right part of the document window as shown here.
