A Tcl/Tk script generates the diagrams into a canvas widget.  The  
script is at:

      http://www.sqlite.org/docsrc/artifact/894

After each diagram is rendered on screen, the script uses the  
"postscript" method of the canvas widget to generate a PostScript file  
for the diagram.  Then it invokes the "convert" utility of ImageMagick  
to transform the postscript into a GIF at the appropriate resolution.   
This only seems to work well on Linux.  I installed ImageMagick and  
Ghostscript on a Mac and the script will run there, but the resulting  
images look really, really bad.
