{"version":"1.0","type":"rich","title":"fresh block","description":"A single SVG canvas displays a short text message, \"Edit the code below to change me!,\" centered horizontally at a fixed vertical position. The example uses D3 v4 to select the body element, append an SVG with a width of 960 pixels and a height of 500 pixels, and add a text element with monospace styling. The code relies on basic D3 selection and attribute methods, such as `d3.select` and `attr`, without any data binding or interaction. The visualization serves as a minimal template for editing and extending with D3.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2ba0ab8db1db187d2543e0d7ff8460eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
