{"version":"1.0","type":"rich","title":"Untitled","description":"This example demonstrates the use of vanilla JavaScript and CSS to handle basic user input and display dynamic text on a web page. It shows a prompt-based grade calculator that assigns letter grades (A through F) based on a numeric score, along with corresponding feedback messages, and also displays the current day of the week using a switch statement on `new Date().getDay()`. The page uses `document.write()` for output and a simple `style.css` file with a custom `g2` element style, though no React or specific data-visualization libraries are involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f7b4752a7da42c59f82fd796f980fd6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
