text: There are also three basic provisions of communication that need to be assessed when designing an infographic – appeal, comprehension, and retention.  "Appeal" is the idea that communication needs to engage its audience.  Comprehension implies that the viewer should be able to easily understand the information that is presented to them.  And finally, "retention" means that the viewer should remember the data presented by the infographic. The order of importance of these provisions depends on the purpose of the infographic.  If the infographic is meant to convey information in an unbiased way, such as in the domains of academia or science, comprehension should be considered first, then retention, and finally, appeal.  However, if the infographic is being used for commercial purposes, then appeal becomes most important, followed by retention and comprehension. When infographics are being used for editorial purposes, such as in a newspaper, the appeal is again most important but is followed first by comprehension and then retention.
  However, the appeal and the retention can in practice be put together with the aid of a comprehensible layout design. Recently, as an attempt to study the effect of the layout of an infographic on the comprehension of the viewers, a new Neural Network-based cognitive load estimation method was applied on different types of common layouts for the infographic design. When the varieties of factors listed above are taken into consideration when designing infographics, they can be a highly efficient and effective way to convey large amounts of information in a visual manner.
