Visual.ly is an excellent source for interactive infographics. Perhaps they’ve had this option for awhile, but I’ve just noticed that they now have an option under each infographic on their site that says:
Click here to embed this graphic on your site
Click on it and you are provided the embed code. It’s a nice addition.
I’m adding this info to The Best Sources For Interactive Infographics.
Visual.ly also lets you create infographics there. However, I’m not very impressed with what they have to offer for that feature — at least for now — so I haven’t added it to The Best Resources For Creating Infographics.
