{"version":"1.0","type":"rich","title":"Untitled","description":"A single orange circle is rendered inside a small SVG canvas, demonstrating basic D3.js selection and manipulation. The example uses `d3.select` to target the circle element by its ID, then modifies its radius, stroke, and fill color via the `attr` and `style` methods. The code shows how D3 can directly update SVG attributes and CSS styles on existing DOM elements, with the circle initially defined in static HTML markup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
