for a general solution, you would probably need for each connection both values:

  • beeline distance
  • "road" distance

    Unfortunately, available datasets do not come that way.

    Most of the time they don't even come with any indication of which type of 'distance' they contain. They are just abstract sets of numbers that might represent time, litres, candles, dollars, similarities etc.

    The dataset's only requirement to be useful for research purposes, is that they have known solutions; and the desire to visualise them does not go away because they are inconvenient.

    In the absence of evidence, opinion is indistinguishable from prejudice.
