+# Graphgen
+
+Interactive database schema visualization. Supabase-style graph of your data model, rendered in the browser.
+
+**Status:** planned
+
+---
+
+## What It Will Do
+
+Graphgen will take a schema definition and render it as an interactive, navigable graph. Tables as nodes, relationships as edges. Click to explore, zoom to navigate.
+
+Think Supabase's schema visualizer, but fed by soleprint's modelgen extractors and rendered with soleprint-ui's GraphRenderer.
+
+## Architecture
+
+```
+Extract (modelgen) ──► Serve (station API) ──► Render (GraphRenderer)
+```
+
+**Extract** -- modelgen extractors read the codebase (Django, SQLAlchemy, Prisma) and produce a normalized schema.
+
+**Serve** -- station exposes the schema as a JSON API endpoint.
+
+**Render** -- GraphRenderer (Vue Flow) draws the interactive graph in the browser.
+
+## Dependencies
+
+- **modelgen extractors** -- must be functional before graphgen can extract schemas
+- **soleprint-ui GraphRenderer** -- Vue Flow-based component for rendering
+
+Graphgen depends on modelgen extractors being complete. That is the blocking dependency.
