So one truly fascinating aspect of legal practice is that we tend to operate in the gray areas. However, the traditional way of researching case law – reviewing a list of cases returned based on your query – does little to help you sort through the mess.
With data visualization, you not only see the cases, but you see the relationship between cases, and how the cases work together.
Among the most significant benefits, the data visualization elements of Ravel Law will help you narrow your research to the most relevant cases more quickly, while also helping you find those cases and arguments that, for whatever reason, didn’t rank in the top of your search.

The value in this appears to relate concepts from one case to others through the visuals on the graph. The larger the circle, the more important the case will be. Lines connect one circle to another circle and it’s very easy to see which major cases are connected to other major cases. This is like a citator on steroids in my opinion as one can get to this point with a simple search. That means multiple steps in developing the analysis that finds the value and use of related cases. The snippets help immensely in determining which related cases are of value.
