{"version":"1.0","type":"rich","title":"Javascript A6","description":"This example demonstrates a blank interactive SVG canvas where a single rectangle with the ID `change-hover` transitions its fill color to green over three seconds when hovered, using CSS transitions. The page sets up basic JavaScript syntax—variables, objects, loops, and functions—commented out for educational reference, but no active D3 or data visualization code executes. The rendering is plain SVG embedded directly in HTML, with no external data sources or libraries beyond standard CSS and JavaScript.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e5e56a4d18743b784f3139b1288e42e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
