{"version":"1.0","type":"rich","title":"Untitled","description":"A blank 600 by 600 SVG canvas is appended to the page, serving as the entire visualization with no data or shapes drawn. The code imports `select` and `json` from D3 v5, but only `select` is used to create the empty SVG container. No further rendering, data loading, or interaction occurs, leaving the visualization as an empty white space. The stylesheet defines a large centered message style, but that element is never created in the HTML or JavaScript.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d642731b86344068c43f1ccdcece75b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
