I recently came across a great tool called Visual Thesaurus…
“The Visual Thesaurus offers stunning visual displays of the English language. Looking up a word creates an interactive visual map with your word in the center of the display, connected to related words and meanings. Click on these words or meanings to explore further.”
It Is available for Mac and Windows as a desktop application, or as an online browser-based subscription service. It’s very cool, you should check it out.
