{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"A scatter of overlapping circles with varied radii, positions, and bright fill colors sits on a pale green background, demonstrating the D3.js general update pattern. The visualization maps an array of circle data objects to SVG `<circle>` elements using `select`, `data`, and `join`, then sets `cx`, `cy`, `r`, `fill`, and `opacity` attributes via method chaining. The code measures the container’s client dimensions to size the SVG, and uses a reusable `main` function to support hot reloading. It highlights D3’s data-driven DOM manipulation with a simple, static composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/589f158a09cc473b9a0e900dc4f8b0c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
