Info graphics marry numerical data to imagery. For example: it's an info graphic if you show some number of cars unevenly distributed across two lanes on a road and explain that each car in lane A represents 10,000 rental cars and each car in lane B represent 10,000 driver-owned cars, and the sum of the infographic cars * 10,000 happens to equal the number of cars on USAmerican roads, assuming that the infographic specifies that its subject is rental-vs-ownership of cars on USAmerican roadways. See? An info graphic is a fancy chart or graph. Every rule from your highschool science textbook about charts and graphs applies to infographics. Pictures that don't adhere to those rules are just pictures.
