Gliffy

Gliffy is a diagram editor that runs directly in your browser. Similar to Visio, Gliffy allows you to create Flowcharts, UI wireframes, Floor plans, Network diagrams and more. Gliffy has two ways to make document sharing simple. Collaboration enables others to see and edit your work by simply entering their email address. Publishing creates a read-only image of your diagram that you can easily embed in a wiki, blog, or other type of web software. Try it out at http://www.gliffy.com/
