Code change visualization turns a list of edited lines into a diagram of components and relationships. It can help a reviewer see which files belong together and how a proposed change moves through the system.
A diagram is an inferred aid rather than a verified model of the code. Useful visualizations preserve direct links to files, symbols and diff sections so every claim can be checked.

Code change visualization turns a software diff into a diagram or other visual map of the affected components and relationships. It helps a reviewer understand the structure behind a long list of edited lines.
For example, a diagram can show that a database change feeds a service and then an interface. The picture is only an aid, so each box and connection should link back to the real files and diff sections where the reviewer can verify it.
