<p>I have a report due soon. I want this report to make a lasting impression on a teacher which I have been having trouble in, therefore I want to do 110% on this. I want to create my very own diagrams from scratch. This diagram I plan to do will probably be a diagram of fission, nuclear fission, and probably a diagram explaning the formula E=mc2.</p>
<p>What I need your advice in is if you know any guides that help you make diagrams... have you done something similar yourself? I know somewhat a good amount of Photoshop 7 but I am clueless when I think about diagrams...</p>
<p>Any ideas?</p>
