The Periodic Table of iPhones infographic from scientificamerican.com (credit to Mark Hobbs at CNET) is an infographic about the materials it takes to create an iPhone.  A PDF version is available for download here.

Key ingredients in the iPhone include so-called rare-earth minerals, elements whose properties make it light, bright and loud.

The key message in this design is obviously a wanring to readers that their iPhones (let’s be honest, this applies to any modern smartphone) are using rare materials that may be hazardous and cause environmental problems when they are mined.  

The design ends abruptly, without an ending.  At the end should be a few key things that are missing:

• What’s the conclusion or call-to-action? What should readers do now that they understand the key message? Is the desired action recycling, participating in protests or choosing a different phone?

• Data sources? This design accompanied a full-text article, but because infographics are shared independently they need to list the data sources for transparency and credibility.

• URL to the infographic landing page so readers can find the original story and full-size infographic?

• Copyright statement.
