{"version":"1.0","type":"rich","title":"fresh block","description":"This example shows a blank SVG canvas with a single instructional text element reading “Edit the code below to change me!” positioned at a fixed coordinate. The visualization is minimal, serving as a starting template for users to modify. It uses D3 v4 to select the body element, append an SVG of 960 by 500 pixels, and add the text with specified font size and monospace family. The code relies on basic D3 selection and append methods, with no data or interactive behavior present.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8efd1b30fa6fca728e1ce484399e26d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
