Regex Visualizer అంటే ఏమిటి?

A regex visualizer creates visual diagrams that represent regular expression patterns as flowcharts. Each node represents a component of the pattern (literal characters, quantifiers, groups, alternations) with arrows showing the flow.

This tool helps you understand complex regex patterns by breaking them down into visual components. It supports all standard regex features including groups, quantifiers, lookaheads, and character classes.
