{"version":"1.0","type":"rich","title":"Circles","description":"This example demonstrates how multiple HTML input elements can control SVG circle properties in D3.js v6. It shows three interactive patterns: a number input that changes a circle’s radius, a dropdown menu that transitions a circle’s fill color via `selection.transition()`, and a range slider that resizes four circles simultaneously. The code uses `d3.select` to bind event listeners and `join` to populate options. The SVG is rendered directly in the DOM, with visual feedback updating in real time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a3d5bac1b604bc381e8def7a055476a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
