Here's a draft visualization of key words and phrases found in Nature journal over the past thirty years.
The video starts with phrases from 1970 and continues until 2007.
Phrases appear on the right in the year that they were first seen, then travel leftwards, disappearing in the year they were last seen.
The size of each phrase is related to how often it was seen relative to all the other phrases.
The hue of each phrase is related to how many distinct journal issues it appeared in - green / yellow phrases are relatively transient while red / brown phrases are stable, appearing in many different contexts.
The data is incomplete (it's a bit sparse after '88) and I took lots of shortcuts to see how things might look, so don't read too much into which phrases appear and when for now... a better version will follow.
