{"version":"1.0","type":"rich","title":"Color and size legends","description":"A legend displays a color scale for four fruit categories—apple, lemon, lime, and orange—as colored circles with matching text labels. Built with D3 v5, the example uses `scaleOrdinal` to map domain values to specific colors and a custom `colorLegend` function that binds data to SVG groups via `selection.selectAll` and `enter()`. The legend is rendered with circle radius, spacing, and text offset as configurable props, demonstrating reusable legend components in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9702aa601bef42f3b5508afc26e4459e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
