Helium showing genetic similarity data. Genetic similarity data is stored in our Germinate database (all-by-all pairwise comparisons) which is displayed to the user by selecting a base node then showing similarity of lines in relation to this node. When the user selects another node the new data is retrieved and displayed. A) A slider allows users to select a cut-off or the similarity values (45-100%) and the results are shows in a sortable table below. The histogram shows the data distribution for the selected line which is one of many indications on the quality of the data. Selecting a row from the table jumps to that line, then updates the visualization accordingly. B) Coloured nodes to show similarity to the base line, and node sizing to show the number of times a line has been used in subsequent crosses (the larger the node the greater the number times it has been used as a parent). C) When a line is selected from the main display only edges joining the selected edge with predecessors or ancestors are shown which reduces display clutter.
