use Perl

It's easy to make a graph, even without installing a module from CPAN. For example, a bar chart:

print <<END_BAR_CHART;

xx
xx
xx
xx
xx
xx
xx
xx
xx
xx
xx                                                      xx
--------------------------------------------------------------------------
Column A                                       Column B

Column A: Programmer potential when you can use CPAN modules.
Column B: Programmer potential when you have to code everything
from scratch.
END_BAR_CHART

This graph should be on everyone's mind (ISP providers and sysadmins included) to remember that Perl+CPAN walk hand in hand and one without the other is a sacrilege.
