Generate Excalidraw scene files (.excalidraw) by writing JSON that the Excalidraw app can open directly. Ideal for architecture diagrams, flowcharts, mind maps, and system design sketches in the characteristic hand-drawn style.
An Excalidraw file is a JSON object with this top-level structure:
{
"type": "excalidraw",
"version": 2,
"source": "https://excalidraw.com",
"elements": [],
"appState": { "viewBackgroundColor": "#ffffff" },
"files": {}
}
Each element in "elements" is a shape with a common set of fields:
{
"id": "unique-id",
"type": "rectangle",
"x": 100, "y": 100,
"width": 200, "height": 80,
"angle": 0,
"strokeColor": "#1e1e1e",
"backgroundColor": "#a5d8ff",
