{"version":"1.0","type":"rich","title":"Circles with D3","description":"This example shows a set of seven colorful circles scattered across an SVG canvas, each with a distinct size, position, and fill color at 70% opacity. It demonstrates core D3.js v7 concepts including data binding, the General Update Pattern, and method chaining via `select`, `selectAll`, `data`, and `join` to render `circle` elements. The visualization uses static, data-driven coordinates and colors defined in a JavaScript array, rendered through an HTML import map loading D3 from a CDN. The code also showcases the `join` API for creating SVG circles within a container sized to the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d67423b84a845019c17ca761b60b619?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
