Perl modules usually have a perl interface, but other programs often have text-only interface.

The amazing program gnuplot has already been mentioned, but it's worth repeating. An alternative is grace, which is also a plotting utility that takes a plain text file as input. It also comes with xmgrace, a front end that generates these files.
