Did you run check.php from a browser? (and particularly check-gdbug.php?)

The two things I know to cause this are memory_limit (unlikely on the 
first node, but it depends how big your background image is, and how big 
your memory_limit is), and particular GD versions (usually in 
Debian/Ubuntu). On Debianish systems, it's particularly awkward because 
the command-line PHP isn't necessarily the same as the Apache-driven 
one, which can hide this issue until you use the editor.

The second one (my guess for this case) is in the FAQ: "... I get a 
blank screen in the editor when I add a node"
http://www.network-weathermap.com/manual/latest/pages/faq.html#gdbug

Basically, drawing nodes uses alpha channels. Alpha channels are broken 
in some GD versions. Normally, you'd see this when using hand-made 
configs too though, so that's a little stranger, although those are 
potentially different PHP setups (web vs CLI).
