The visualization of gay rights in the US is definitely an exceptional work. I find that the visualization is simple, intuitive and yet one can effectively understand gay rights in different states.
The first thing I like about the visualization is the usage of concentric circles. This is an excellent way to represent rights in individual states (along with regions) as this saves a lot of space and each state is depicted in the same chart. The placement of legend in the interior of the chart is also strategic as the traditional legend space is used for highlighting of rights of individual state as selected.
The second thing I like about the visualization is the coverage of various topics and simple representation of the “Maximum”, “Minimum”, “Prohibited”, “No law or unclear”. This visualization makes use of different colors/patterns to represent and hence does not require more than one chart to represent different states.
The chart is also not over crowded and the reader not feel overwhelmed by the information. Hence even though the information is represented in one chart, utilization of concentric circle makes the representation of gay rights across 50 states for seven different attributes simple yet intuitive.

Interesting visualization over an exceptional topic! With the use of concentric circles the author has dived deep into the subject and covered most of the facts in order to create awareness. Great job!
