Visualization of data of whichever type makes the data easier to take in. It is no difference with corpus data. There is a large amount of techniques to extract corpus data from, such as dictionaries, thesauruses, collocations, frequency statistics, etc. For easier study of natural language, sorted data can be easier to look at in graphical form.

Visualizations posted on this website are focused on features that provides Sketch Engine. These features are Word Sketch and Sketch-diff. And use the corpora of English language - Araneum Anglicum Minus and Czech language Bruna Bohemica.

Word Sketch displays the collocations of the words, due to the highest score of salience.
Sketch-diff displays the collocation in comparison between two headwords, and makes it visually distinguishable to define which word has stronger connection in collocation with first or second headword.
