Easel.ly makes data visualization easy. This free tool allows you to select and drop backgrounds, objects, and text onto a canvas to create your customized infographic. After you register with the site (so you can save your work), you can start from scratch with a blank canvas or you can edit an existing theme.
Your infographic can be saved as a JPEG and added to your LibGuide using a Rich Text / HTML box or any other box type that allows graphics.
