[Omaha.pm] Fishing for GUI ideas...

[Todd Christopher Hamilton]

xml is a great idea. I agree it might be to much to render but...what
if you approached it like a large table.  the million row table
problem has (AFAICT) has been solved with the concept of pageing.
paging like displaying only 50 rows of you million row table.

what if you took a similar approach with your svg? each zoom level
displays only what you need.  new zoom requests (ajax) make a new
query in the background.
