{"version":"1.0","type":"rich","title":"Fork of Circles","description":"This example demonstrates three interactive D3.js controls that update SVG circle properties in real time: a numeric input resizes a circle’s radius, a dropdown menu transitions its fill color, and a range slider adjusts the radius of four circles simultaneously. Built with D3 v6 and loaded via UNPKG, the code uses `select`, `append`, `data`, `enter`, and `transition` to bind HTML elements and handle `input` and `change` events. The visualization runs entirely in the browser with SVG rendering and animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cfe3427f1e5428994a366a6ce597df3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
