{"version":"1.0","type":"rich","title":"Hello VizHub!","description":"A single gray circle is centered on a solid background, demonstrating a minimal D3.js visualization. The code selects an SVG element using `d3.select` and appends a circle, setting its radius and positioning its center coordinates. The example imports D3 v5 and uses an ES6 module to define a message string, though the message is not displayed. The page relies on a stylesheet for typography and layout, with the circle rendered entirely through D3’s SVG manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/742722e8e328477b834195204d1d0299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
