# Mermaid Tidewave Web can render Mermaid diagrams, all you need to do is ask your coding agent to generate one! You can use Mermaid in Tidewave for: * Visualizing existing code: Tidewave could analyze existing code and generate diagrams to help developers understand relationship between modules, files, etc * Documentation generation: after implementing a feature, Tidewave can generate sequence diagrams showing the request/response flow, architecture diagrams, state transitions, and others * Database work: given Tidewave's ability to execute SQL queries, it can generate ER diagrams, relationship diagrams showing foreign keys and query execution plans as flowcharts * Debugging and analysis: you can ask Tidewave what happens when it executes an action (such as clicking a button or filling in some form), and it will cross-reference client side actions with source code and logs Check out this 3-minute demo for a more extensive example of using Tidewave to generate Mermaid diagrams for debugging and analysis.
