{"version":"1.0","type":"rich","title":"Color and Size Legend","description":"This example demonstrates two custom legend components built with D3 v5: a categorical color legend for fruit categories and a quantitative size legend for a numeric scale. The color legend maps ordinal domain values to a range of colors using `scaleOrdinal`, while the size legend uses `scaleSqrt` to translate tick values into circle radii. Both legends render as SVG groups with circles and text labels, with spacing and offsets applied via `attr(\"transform\")` and positioned within an `svg` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c60aa3af1c0641b4a37910bd9923b378?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
