If you are looking for a few free resources to help you create a great infographic, here’s a few that I’ve used. I can’t say that there is one that I like better than all others…only that each has it’s value, depending upon what you want to accomplish.
Venngage – Allows you to create a dashboard of multiple infographics on one page. Has a variety of graphics templates, color themes and charts.
Piktochart – Piktochart & Venngage or very similar. Each has it’s own set of graphs, color themes and templates.
Dipity – Helps you develop visually engaging timelines
Get About – Helps you visualize your social media impact.
