Comparative Analyses of Interactive Trees


General Principles

These general principles for an interactive tree of life application emerge as a result of comparative analyses of various current approaches, particularly while keeping the target audiences in mind.

  • Common names should be shown and thoroughly supported.
  • Give an automatic preview of the contents of the next level down & enough information to help the viewer decide which branch to follow
  • Provide Search capabilities for locating specific & general targets on the tree.
  • Support spelling correction for search terms.
  • Provide an overview of tree's structure & depth, and an indication of where the view is currently located.
