Interactive phylogeny with metadata. A screen capture showing tree-based selection from an interactive phylogeny that can be manipulated to expand/contract clades, and from which clade and individual genome selections can be made. Metadata is shown appended to each leaf node of the tree, and branches containing more than one genome have the metadata for the entire branch summarized as an interactive bar-chart. Each colored bar represents a metadata category, which is summarized in table form when highlighted; here the red bar representing Isolation Host is shown with a frequency table of hosts. Metadata represented as bars are as follows: Green:Serotype, Red:Isolation Host, Blue:Isolation Source, Purple:Symptoms/Disease, Orange:Stx1-subtype, Teal:Stx2-subtype
