{"version":"1.0","type":"rich","title":"Fork of Color and Size Legends","description":"This example demonstrates two common legend types: a color legend mapping ordinal fruit categories to distinct hues, and a size legend using a square-root scale to map numeric values to circle radii. The SVG renderings use d3’s selection API (`selection.selectAll`, `selection.enter`) and custom legend modules (`colorLegend`, `sizeLegend`) that generate tick groups with shapes and labels. The color legend uses `scaleOrdinal` with explicit color ranges, while the size legend calls `scaleSqrt.ticks()` to compute interval breaks, with circles stylized via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60def3a32aab4cbcb01e30b978d8226a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
