## Description

regex-vis is a set of tools for the visualization, editing, and testing of regular expressions. It provides a visualizer that generates structural maps of patterns to clarify how they parse and match text, alongside a visual editor for modifying patterns without manual character entry.

The system includes a regular expression tester to validate patterns against sample strings. These tools enable the debugging of pattern matching behavior by visualizing the internal structure of the regular expression.
