{"version":"1.0","type":"rich","title":"AN","description":"This example displays a placeholder visualization on an SVG canvas, showing a large monospace text prompt that invites code editing. The page initializes a 960-by-500-pixel SVG and sets variables for block dimensions, spacing, and layout—though these are not yet used. It uses d3.v4 to append the SVG and a text element, relying on the D3 selection and attribute APIs. The visualization is built with Blockbuilder.org scaffolding and renders solely through SVG elements, with no data source or interactive behavior implemented yet.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4b7cc918a28fca17214dd5b005054176?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
