WPF: Tube Planner Using A Guided Search

I recently came back from holiday and decided I needed to ease myself back into work gradually.

I have to say I am most pleased with the result.

  • Panning
  • Zooming
  • Station connection tooltips
  • Hiding unwanted lines (to de-clutter the diagram)
  • Information bubble
  • Diagrammatic solution path visualization
  • Textual solution path description

As always, if you fancy leaving a comment or a vote, that would be cool. Thanks.
