Piktochart is a good tool to use.
Piktochart provides seven free infographic templates. Each template can be customized by changing the colors, fonts, icons, and charts on each template. If you need more space on the template, you can add more fields at the bottom of the templates. If you need less space, you can remove fields from the templates.
Applications for Education
Piktochart could be an excellent tool for your students to use to create infographics based upon data that they research or gather on their own. Some student infographic projects that I've seen include comparing development data and community demographic data.
