The overall goal of an infographic is to provide a visual synthesis of your message in context. As is evident from the name the information is represented through images and relies heavily on graphics (not words) to relay the key ideas and meanings.
Typically, you will be asked to use a tool such as PowerPoint or Piktochart to create a visual representation of the relationships and connections among and between facts, concepts, theories, models, etc for the subject matter you are studying. (Limit text, but remember citations and references.) For example, in PowerPoint, one slide of 10X20 inches can be developed using graphics (rather than text) to convey ideas and map your mental model of a subject. (To adjust the size of your slide in PowerPoint, go to Design, and then Page Setup.)
As noted above, it is important to cite sources and provide correctly formatted references, even for infographics.
