It’s an free English online thesaurus that helps you find the meanings of words and show connections among associated words. You can easily see the meaning of each by simply placing the mouse cursor over it.
Underneath Graph Words lays the WordNet - a large lexical database of English. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. These meanings and semantic relationships are revealed graphically by the HTML5 canvas made available by Graph Words.
To search for associated words, type the word in the search box at the top of the window and press the "Draw" button. You may also press the enter key instead. After searching for a word, the main display will populate with visual thesaurus. The word you searched for will appear in the center of the display, and will be surrounded with words and meanings that are related to it.
