{"version":"1.0","type":"rich","title":"Fork of Color and Size Legends","description":"Two reusable D3 v5 legend components demonstrate categorical color mapping and quantitative size scaling in SVG. The color legend uses `scaleOrdinal` with domains like apple, lemon, lime, and orange, while the size legend employs `scaleSqrt` to map a 0–10 range to circle radii, with ticks generated via `sizeScale.ticks`. Both render grouped circles and labels, with the size legend filtering out zero values. A video tutorial link accompanies the code, and the styling includes custom font sizes and stroke opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cec902bfc1fd4aa29fdbebfb47fd8cd4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
