Default Stellar Cartography in a 2d universe

While working on several approaches in an attempt to map 3d stars into 2d charted space, I noticed something: there are large volumes of space close to the sun that are unreachable without high jump (>2) drives. From the Sun away from the core and at positive angle +z, there's really nowhere to jump to. (The attached plot is opacity and color coded for point distance to the nearest star. Opaque Orange spaces are the furthest away (most inaccessible).

I know that the 3d vs 2d discussion about Traveller has been going on for ages, and by and large it seems that most Traveller players prefer 2d. To me, the 3d map makes the universe feel much more vast, even when looking on close in spaces:

Barnard's Star doesn't seem crowded in by a bunch of other stars, like it kind of does (to me) on the 2d map.

In Traveller canon, Junction (Wolf 359) has two stars that can be reached by Jump-1 and in reality, no stars can be reached from Wolf 359 with Jump-1 (Lalande 21185/Midway is 1.25 parsec away).

I'm sure this has all been talked about many times before - is there an ongoing megathread about it somewhere?

Anyway, my question:

In canon, can starships jump into empty space? Interstellar Wars (is that canon?) implied that they cannot, a jump point - some kind of massive body in interstellar space - has to be identified to jump to and then make a further jump to get to a destination. I believe that it mentioned that the first flight to Barnard's Star was done in this way.
