Infographic designers everywhere, prepare to get your game up. Infogr.am is a service which enables you to create infographics online without having to use any design programs like Photoshop or InDesign. You simply choose a template and then fill it in with your information.
There are various templates for various different types of data you might like to present. There isn't much customisation for each infographic though, you usually have to use the colours you are given. You can't have it all your way right?
The service is relatively new so they are continuing to work on it and create new templates. Hopefully as the service evolves, infographic templates will have more customisation features.
It is in BETA stage so the service isn't fully ready, there will be bugs. However from my use I found it to be relatively a smooth experience.
If you're not a designer and don't know how to use programs like Photoshop, I highly recommend using Infogr.am, it's the next best thing.
