I've used some answers here to help make figures and do other things in documents I've created.
To make the question specific, consider this question - drawing oddly shaped nodes to contain existing nodes in tikz which will affect a figure I'll be publishing soon.
Now the question comes - how do I attribute this?
So my question is basically - do I just need a comment in .tex file saying
%this method comes from <url>
or do I need something in my bibliography?
or something directly where the figure appears in the text?
