Show most similar and dissimilar entities
I may want to see examples of entities that are most similar and most dissimilar.
For example, Lalitpur (MP) and Chitrakut (MP) are extremely similar though in different states. On the other hand, Mon (Assam) and Diu (Daman & Diu) are as dissimilar as two districts can be.
The interface for this would list the 50 most similar pairs of entities (with keys) and the 50 most dissimilar pairs of entities. Against each, it should also list the Euclidean distance. (The Euclidean distance should be computed on a normalized scale, of course.)
Clicking on any of the pairs should show a popup with a table of all features of both entities side-by-side. The table values should be the actual values. The table cells should be colored based on the relative value. (For example, if Female % ranges from 0.40 to 0.50, a value of 0.42 would be colored orange, 0.45 would be yellow, etc.)
