I am doing a presentation at work regarding a patient who presented to the hospital with diarrhea after travelling extensively throughout Africa and Asia. I thought it would be interesting to present his travel history (relevant to the types of infections to which he would have been exposed) as a series of maps with a traveling dotted line (similar to the way travel is designated in the old Indiana Jones movies. Anyone know how I can do this? Ideally I'd like to work it into a Keynote or Powerpoint presentation. Thanks!
