{"version":"1.0","type":"rich","title":"Color and Size Legends.js","description":"Two reusable legend components render D3 scales as SVG groups. A color legend maps ordinal fruit categories to circle fills using `scaleOrdinal`, while a size legend uses `scaleSqrt` with `ticks()` to generate circle radii. Both employ the enter-merge-exit pattern and rely on `selection.call()` to attach legends to the SVG. Text labels and circles are styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28fa6ac16ec042bc8d5e4423053cb011?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
