This is a tool for visualizing collocations. It is used to visualize the distance between components in multiword expressions. Since some word combinations are more rigid than others, the visualization of collocations can show whether the word combination is “tight” or “loose”, how many words are between the individual components, and how frequently they occur together. Some combinations are fixed, while in others, the second word may be expanded with other attributes
