{"version":"1.0","type":"rich","title":"upload tester","description":"This example shows a file upload interface built with React. It displays file details such as name, type, size, and last modified date after a user selects a file. The component uses the `useState` hook to manage selected file state and a form data submission. It sends the file to the freeimage.host API via a `fetch` POST request using a placeholder API key. The rendered output conditionally shows file metadata or a prompt to select a file, and includes a submit button.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7bc1c4d661146b59e1fae71401cd4a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
