May be we can also draw a geographical overlay to show if words from one region relate to other. It's fascinating how words travel through space and time ! Their pronunciation and meaning both can change over time and space. It will be a fun to show somehow how the Portuguese word 'Igreja' (church) became 'Geerja' in Bangla. And also these connections reflect a view of world history. The similarity between Greek and Bangla/Sankskrit words for the numbers one to ten compelled me to explore more about Indo-European history.Visual Thesaurus and VisuWords are online graphical dictionaries , they show connection between words . As human brain works, it is always easier to learn about something new if we can relate this to some other thing of our previous knowledge, so this connected words may relate to some words we already know and thus help our learning process.
Here you can see the graphical representation of the word "country" , showing connection between words with similar meaning. The first screenshot is from Visual Thesaurus, but I think VisuWord does a better job by giving examples. But both this applications are English to English, so if you are looking for translation, this may not be the right place.
And while I was searching the web for word visualization, I found this nice article about Visualizing vocabulary.
