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,
