Infographics tend to fall into two basic categories: stylized data presentations and narratives. The former, such as this piece on customer satisfaction and loyalty, don’t necessarily convey any more information than basic charts and graphs in a conventional report or webpage would, but their communication value lies in their ability to catch the audience’s attention and the ease with which they can be distributed online.
The latter go beyond this, taking full advantage of the visual medium to tell stories or show interconnected processes. These infographics can be powerful communication tools, even to the point of replacing conventional reports. This infographic from the Sustainable America initiative, for example, uses the infographic format to explain how to compost successfully even if you live in an apartment. Narrative infographics can become quite elaborate, such as this animated piece on the story of coffee production.
For a class activity, ask students to find several narrative-style infographics online (visual.ly is a good place to start) and analyze their storytelling effectiveness. Does each infographic tell an effective story? How does it use emotional and logical elements to make its case? Does it use any suspect or oversimplified information (failing to differentiate correlation and causation seems to be a common sin among infographic designers)?
Creating professional-quality infographics is beyond the reach of the average business communicator, but if you'd like to have students give infographic design a try, they can draw sketches by hand or use the simple graphical tools in word processing or presentation software.
