{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"This example creates an animated night sky using 200 randomly positioned stars and five larger planets rendered as SVG circles. Each star twinkles by continuously varying its opacity through a recursive transition loop, while the planets maintain a constant opacity. The visualization uses D3.js’s `select`, `join`, and `transition` APIs to bind data arrays containing position, radius, and color properties, with attributes like `cx`, `cy`, `r`, and `fill` set dynamically. A radial gradient background simulates deep space.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e1c460b00d5348d8aa42d1a5efaff48a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
