Gliffy lets you piece together various types of diagrams, ranging from flowcharts, floor plans, and process charts. Simply drag shapes from the left panel into the document, add text, and link the shapes together with the line tool. There are plenty of different images and elements so you can organize your data.
Once created, you can sign up for a free Gliffy account and save your work on the website, or export it out as a JPG so you can print your chart out.
