When I went on the hunt to find some apps for the iPad which would allow the class to create their own infographics, I really could not find much. I have pasted two links below for two apps I thought would be suitable
https://itunes.apple.com/am/app/dropvis/id588954097?mt=8&ign-mpt=uo%3D4 – Dropvis costs $1.99 and allows you to create ifographics on the iPad.
https://itunes.apple.com/am/app/prezi-for-ipad/id407759942?mt=8 -Prezi for the iPad also produces infographics but in a more interactive way. This app is FREE.
