So I tried it:

 triton:~/s/FlameGraph> ls -l flame.svg 
 -rw-rw-r-- 1 mingo mingo 1022870 Oct 10 09:06 flame.svg

but when I tried to view it via ImageMagick, it first showed an empty screen:

 triton:~/s/FlameGraph> display flame.svg 

then when exiting it said:

 display: non-conforming drawing primitive definition `text-anchor' @ error/draw.c/DrawImage/3182.

although I guess that latter is an unrealted ImageMagick problem, not caused by 
the SVG.

Thanks,
