A wireframe is a visual guide to the layout of a site, focusing only on structure, not on the site’s look and feel.
Your set of wire frames should include mock ups for your intended
Home page,
Item page,
Visualization heavy page,
Text-Based Details page, and
Generic About page.
To draw your wireframes, you can use Axure, Photoshop, Visio, PowerPoint etc. Make sure though it is converted into a PDF for readability when being submitted.
