title: Connecting locations on map with Python with data illustrated
body: <p>I would like to illustrate the density of flights from says Melbourne to other cities in Australia on a map. Ideally, we would have arrows (connecting a city to the others) with their thick demonstrate the number of flights in a day from one city to the others. Do we have a lib for this job?</p>
  
  <p>Many thanks in advance for your inputs.</p>
  
  <p>Kind regards,
  HH</p>
