Michael, you are making one mainly huge mistake in your map...
Maybe you have not noticed, but OP has placed systems on the map according to where to jump gate for that system is...
For example, if jump gate to Guangdong from Gladius was in Gladius in sector C7 (lower left), then Guangdong would also be placed lower left to Gladius on the universe map.
All you did was create a map which connects connectable system without geographical accuracy
Nice try, but not enough.
P.S. my notebook map may be uglier, but it sure is more accurate
