A part of data analytics is to identify and distinguish a visualization and an info-graphic. They both are pictorial or visual representations of data; however, it is essential to use the right kind of representation based on the type, amount, context and relevance.
A data visualization is usually a representation of data as it is- without much editing and processing, usually representing the data as it is. They are mostly automated visualizations generated through algorithms or programmed codes. We can basically say that a data visualization is bound to tell you about the same data in a different way. It does not try to tell any story by itself.
Info-graphics on the other hand can be elaborate diagrams that tell you something using a lot of illustrations, graphics, pictures and icons. An info-graphic can be modeled, modified and designed to make the user look at it in a way or convey a particular message. Info-graphics can be creative and illustrious and omit some data to make the visualization fit the story line.
Again, all visualizations can be considered as info-graphics but the opposite is not true.
