Infographics are an effective way to convey information quickly to a general audience. Infographics can also help people remember facts and figures. People understand and recall information presented with images better than with text only.
Infographics come in many forms. They can be a simple visual display of data or an idea, or the can depict more complicated stories. See some examples below, or search the web to see many more.
What shape your infographic takes will depend on whether this is a single point (e.g. a fact or description of data), a narrative point (e.g. about the cause and effect of something), or about it about how a process works. What level of knowledge does your intended audience have about the subject? What are their interests, so what visual cues will help them to understand and remember your key points?
Many of the example you will see online are quite complex and have sophisticated graphs (and many are just not that good). Keep things simple. You do not need to have complicated graphics. Some of the most effective infographics are very simple.
