For my local hacker/maker space I want to do some etched copper plates that have stylized algorithmic functions on them. If you've seen etched PCB circuits then you're familiar with what I'm talking about.
The graphing software I have, though, doesn't allow me to manipulate the line weight (for the individual functions) or image export properties enough to get the result I'm looking for.
What are some free or low cost graphing utilities that offer relatively customizable function aesthetics?
