{"version":"1.0","type":"rich","title":"Svelte + D3: Generation of a phyllotaxis layout","description":"A spiral of 1,000 circles is rendered sequentially, each positioned by a phyllotaxis layout using the golden ratio. The animation progressively reveals circles while drawing a connecting spiral path through their centers. Circle colors come from D3’s `scaleSequential` with `interpolateWarm`, and the layout is generated by a custom `layoutPhyllotaxis` function. The SVG and animation are built with Svelte’s reactive `$:` blocks and `each` loops, updating at set intervals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8e10cb65ef647328d607e53f513bde9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
