{"version":"1.0","type":"rich","title":"Document","description":"This example shows a minimal HTTP server that serves a single static HTML page titled “Document.” The Node.js code uses the `http` module to create a server on port 3000, responding to requests by reading `index.html` with `fs.readFile`. If the file is found, it writes the HTML content with a 200 status; otherwise, it returns a 404 error. The served page contains only a heading, “Server,” demonstrating basic file serving without any client-side visualization libraries or data rendering.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-43782e019237ed4ea4fd1fa67149980f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
