{"version":"1.0","type":"rich","title":"Fork of Svelte + D3: Canvas & renderless components","description":"Ten thousand tweened circles animate across a full-screen canvas, cycling through new random positions and radii every two seconds with a magma color scale. The Svelte example pairs a renderless Canvas component with a Circle component that registers draw functions via Svelte’s context API, using `d3.scaleLinear`, `scaleSequential`, and `interpolateMagma` for mapping. Each circle’s attributes transition smoothly through `tweened` stores with `cubicOut` easing, while `requestAnimationFrame` batches canvas redraws for efficient animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a29386001434257b123cf2029c65c86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
