=item I<filename>
The name of the graph to generate. Since B<rrdtool> outputs
-GIFs and PNGs, it's recommended that the filename end in either
-F<.gif> or F<.png>. B<rrdtool> does not enforce this, however.
+SVGs and PNGs, it's recommended that the filename end in either
+F<.svg> or F<.png>. B<rrdtool> does not enforce this, however.
If the I<filename> is set to '-' the image file will be written
to standard out. All other output will get suppressed.
-PNG output is recommended, since it takes up to 40% less disk space
-and 20-30% less time to generate than a GIF file.

If no graph functions are called, the graph will not be created.
=item B<-s>|B<--start> I<seconds> (default end-1day)
=item B<-w>|B<--width> I<pixels> (default 400 pixel)
Width of the drawing area within the graph. This affects the size of the

=head1 NOTE on Return Values
Whenever rrd_graph gets called, it prints a line telling the size of
-the gif it has just created to STDOUT. This line looks like this: XSIZExYSIZE.
