{"version":"1.0","type":"rich","title":"Svelte + D3: Phyllotaxis layout (irrational 2)","description":"A generative arrangement of 1000 circles follows a phyllotaxis spiral, offset by an irrational angle derived from 1+√2. Each circle is colored with a warm sequential scale from D3, and the innermost circle briefly turns transparent in sequence via a timed activeCircle index, creating a wave-like fade. Rendered as SVG within a Svelte component, the layout is computed by a custom `layoutPhyllotaxis` function using D3’s `scaleSequential` and `interpolateWarm` for color mapping, with smooth CSS transitions animating the opacity changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49ea3f2179e64db1b2a208ecfde3a375?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
