Tip for Usability – If you can, try and use graphs and images.
Images tell a lot of things, more than words.
Whenever possible, use images, as opposed to just using words.
I recently did a paper for a school I currently attend, and having graphs and images helped a lot.
Animations or live demos are even better, but it takes more work.
Whenever you have a paper to prepare, consider images, they have a big impact.
