This example turns a Raspberry Pi camera into a simple web-accessible remote snapshot service. The Python script uses the standard `http.server` and `socketserver` modules to run an HTTP server on port 80, with a custom `GetHandler` that responds to the `/photo/` path by launching `raspistill` via `subprocess.Popen` to capture a JPEG to `camera.jpg`, then instructs the browser to load that file. Any other request falls back to the default `SimpleHTTPRequestHandler` behavior, serving static files from the current directory. The visualization is thus a live photograph retrieved on demand, with no charting or rendering library involved.
