The analytical views area gives you a breakdown of the results in your results list, grouped by different attributes of the data, such as researcher, research organization or funder etc.
The two visualisations available are in the "Overview" section, and the "Compare" section.
The overview section shows a trend line over the past ten years for the type of data you are looking at. In the above example it is publications.
The compare section allows you to make a comparison between any two research organizations or funders, based on the data type you are searching, broken down by the Fields of Research classification system (see below for publications at Oxford versus Cambridge).
