{"version":"1.0","type":"rich","title":"计时器","description":"This example presents a functional digital stopwatch interface built with React. It displays elapsed time in hours, minutes, seconds, and milliseconds within a text input field. Three buttons control the timer: start, stop, and reset. The implementation uses JavaScript's `setInterval` and `clearInterval` to update the display every 50 milliseconds, incrementing time values and handling carry-over between units. The interface is rendered as plain HTML elements with inline event handlers, showing a simple interactive time-tracking tool without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/978d26d0ae244c6a81b61c6deed2251e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
