Interactive infographics are data-rich, visually compelling and engaging infographics that also utilise subtle animation and responsive features so users can interact with the design.
In essence, viewers can discover information and interesting facts on their own by scrolling, clicking, unfolding, panning and zooming over the infographic. These movements trigger the functions within the design to display additional relevant content.
Animated infographics are an elegant and powerful way to explain dense subjects without bombarding the reader with information or crowding the screen with text.
Common examples include:

Maps/globes

How-to guides

Timelines

Flowcharts

Informational charts/cheat sheets

Custom questions/quizzes
An interactive infographic is a superior form of a static infographic. The interactive experience allows for more interesting data visualisation, dynamism in the types of information that can be presented and greater user engagement.
Interactive elements can easily turn a good infographic into a great infographic.
