Making sense of large data sets has always been a daunting task, and every tool that makes the life of an analyst easier is worth exploring. There are 45,000 observational studies on the CT.gov database. This is how trial version of IBM Watson visualizes the data available. The dataset was minimally processed to reflect priority information requirements, in this case insight into the most commonly used study designs over time.
