If you click on A, you will be able to see if it is close to B or not. Or, more generally, clicking on a few points in a cluster on this map should give you an idea of whether you'll be able to travel easily between places once you get there. So I don't think it's as useless as you are making it out to be.

Then again, I fail to see how this is a major improvement over just clicking the first location of interest in an ordered list to generate a new list etc.

My main point is that to me, you're either interested in going to the closest location from where you are, and you'd probably want a brief description of each location to filter out points of interest to you. A list is just as good if not better (since you can quickly glance more information about each place) for that purpose.

Or else you're interested in the geography of the different locations or their exact spatial relationship and then you need a normal map anyway.

Sure, this is a neat geographic data visualization, but I just can't see myself using it in a real world situation.

The system could also split the clusters based on proximity. A simple line between groups of nearby features.
