This example visualizes a system-wide entity-relationship (ER) diagram for a rental platform, showing business entities such as users, houses, bookings, and chat sessions, along with their attributes and relationships. The graph uses a neato layout with explicit node positions to arrange boxes, ellipses, and diamonds, and disables overlap with splines for clarity. It renders the DOT definition from the provided file into SVG using the Viz.js library and its full.render.js module, calling `Viz(dot, { format: 'svg' })` to inject the resulting graphic into the page’s `#graph` div.
