Visual Dictionary

Quite often we come across the need to look up the definitions or synonyms for a particular word. Though sites like dictionary.com or merriam provide the service, the problem is that they don't easily convey the context or its relationship to other words. If this can be conveyed in a compact visual manner its easier to remember the word. Look at this site which displays words as a graph with all its relations centered around the word you are searching for.

At the bottom of the graph there is a legend which explains various relationships. Wish I had this during college days, atleast my English wouldn't have been pathetic
