I find interesting the Mashable x Samsung at the bottom

Yeah, what's up with that?

The original infographic was published by a Mashable account to Visual.ly, meaning they produced it and intended to share it in this community (also offsetting storage, but that's moot for such data).  Therefore, I bet it's a promotional arrangement btw Mashable and Samsung for Mashable to create (OR FACILITATE THE CREATION OF) visual assets and also distribute among social media channels.  If you check their account, I bet there's a number of these.  In fact, with Visual.ly offering itself as an Agency/Service Provider of sorts, it's possible Mashable itself did not create this in-house.You know how SEO is.  Infographics (and concurrent Pop Culture infographics) have joined Numbered Lists and How-to's as high traffic items now, post-Pinning and micro-blogging.

Infographics are BETTER than listicles and how-to's for re-pinning and re-blogging and tweeting.

well, right, since the share methods are visual by nature.  i wonder how re-pin/blog stats have affected results differently from previous SEO/pagerank world.  i wonder how the new Hummingbird algorithm takes this into account, if at all.
