You would add several systems and it would display them in a matrix like this, showing the distance relation between all systems.

Use Case: just this past weekend, I wanted to jump my carrier to a system that was within X ly range from both HIP 20567 (Indra, S1) and HIP 19870 (Indra spire site, S2). To find the right one, I first used your
system search to find all closest systems to S1 then all closest systems to S2 (within the specified range), then had to check the distance of all candidates to both S1 and S2
one by one until I came up with the right destination system. Very time-consuming.
With EDU's tool, I would enter S1, S2, then closest in-range candidates from both of those systems and I would find the desired destination in no time. Very simple tool yet extremely helpful.
Hope this helps. o7
