The 3-D nature of the flow?

     I recently obtained a 2-D chart of the flow from a webpage
     (http://www1.tpgi.com.au/users/ibowley/elljam/flow.html).  This chart
     that shows most of the popular/known spheres and four major Phlogiston
     rivers (Krynn, Grey, Inner Arcane and Outer Arcane).  It also suggests
     significant regions outside the area represented (Scro space and the
     Veloni Empire?) I realise this is just a "players map" and hence may
     not necessarilly reflect 100% was the true perceived nature of the
     'flow is.  Is this the only chart out there?

     Something that I've been thinking about is that the flow is actually
     3-D.  I've been struggling with a way to represent this (and maybe
     even maintain the same orientation shown on the 2-D Phlogiston chart I
     already have).  It would be cool if it could be done, as then there
     would be a sort of "hidden" truth buried in the common knowledge of
     the players.  I reckon this would be sorta like the situation in
     Europe in the 14-15th century when most travellers had a pretty good
     idea about Europe but still thought in terms of a flat Earth.

     Has anyone else thought about this or tried to assemble a 3-D chart of
     the known spheres?
