Fork of Circles with D3
A colorful set of overlapping circles is drawn on a light green background, each with a distinct radius, position, and vivid fill color, and a shared opacity that creates blending effects. The visualization demonstrates D3's data join pattern and method chaining, binding an array of circle objects to SVG `<circle>` elements using `select`, `selectAll`, `data`, and `join`. The code sets the SVG dimensions from the container's `clientWidth` and `clientHeight`, and uses D3 v7 via the VizHub CDN configuration in `package.json`.
