{"version":"1.0","type":"rich","title":"Fork of Circles 5/6","description":"This example demonstrates a single D3.js interface that controls three independent visualizations: a numeric input resizes a circle, a dropdown changes a second circle’s fill color via transition, and a range slider adjusts the radius of four circles rendered in an SVG. Built with D3 v6, the code uses `d3.select` to target HTML elements and SVG containers, appending circles with `.attr` and applying smooth color changes via `.transition().duration()`. The dropdown options are generated using `.join('option')`, while the slider updates circle radii through an `.on('change')` event listener.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a72e52334022472683ea83e767323f47?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
