Academic Literature Visualizations

Here's an interesting resource for people who are actually interested in what the science shows about a given topic.

Open Knowledge Maps is an academic literature search engine, but it includes a visualization that categorizes the journal articles.  Click on one of the circles and it zooms in to show the specific articles.

Another nice thing is that it shows which articles are open access and therefore can be downloaded directly.

The example above (which I know is a little small to read), is a search on "Climate Change."

Because there are a lot of scholars out there who do NOT have access to research databases through university libraries, Open Knowledge Maps joins Google Scholar as a key way of exploring the academic literature to see what the peer reviewed scientific literature says.
