  • Clickable interaction w/ Tree Viewer
    • In working through requirements (NESCent Visit), a clickable interaction available from a Tree Viewer will be essential in providing Target TR Users with a proper interface
      • However, a prototype version may look to include different approaches. But in a final version of the Discovery Environment Perspective for Tree Reconciliation - this ability will be priority.
• Adam demo'd an OpenLayers tree viewer that enables panning and zooming in a "Google Maps" like interface. (link)
  • discussion of a need to creating "clickable areas" or "hotspots" for user interaction
  • need to be able to map "events" (in Tree Reconciliation context: Gene Duplication/Loss, Horizontal Transfer, etc)
• Hyperbolic Tree & Tree Reconciliation
  • Want to provide 'semantic zooming'
  • "Linked Hyperbolic" approach
    • This approach needs to be explored in a future Tree Reconciliation working group meeting (and Andrew L. needs to give advance warning to Adam when this is on the agenda).
      • Target for including this topic is March 15, but will be discussed March 1
  • Shapley's Green Plants Tree
