For those new to infographics, these are images which use visually appealing graphics to present information in an engaging and easy to understand way. If you want to show some form of timeline, or the history of a topic an infographic is a good way to do this, as many people tend to zone out when presented with a history of anything!
Of course there needs to be a good balance between the info side and the graphics side – if the text is great but the design is shoddy, it simply won’t work. Nobody would get the useful information from it if they don’t want to read it! Similarly, the best graphics in the world won’t make the poor text any more understandable!
