This example presents a user-input form for collecting metadata about video uploads, including category, day, time, weather, and air quality. Built as a plain HTML page with inline JavaScript, it uses radio buttons organized into named groups to capture the five selections. The `get_X_INPUT()` function iterates over these node lists to store the chosen values in a `user_info` array, logging the result to the console. No external styling or rendering libraries are used beyond basic CSS and DOM APIs.
