Nice idea, but there is no third dimension (distance) with astro data.

Plenty of star databases include distance estimates. They're based on trigonometric parallax, absolute-brightness phenomenon, redshift, etc.
Stellarium wouldn't be so much fun without it.

Not so for the one salva pointed at.
But, in any case, given a sphere of ~250 light years radius, and 600,000 (or even 2.4 million) points, how much clustering would you expect to find?
On average, that comes out to one star(or visible entity) in every 1e40 cubic kilometers of space. And that assumes that all 2.4m objects in the DB are visible to the naked eye which I doubt.

I am sure that some databases include the distance, though maybe not with the resolution you need.
