{"version":"1.0","type":"rich","title":"Legend","description":"This example demonstrates a reusable categorical color legend with colored circles and matching text labels for fruit categories. Using D3 v5, the `colorLegend` function creates a group per domain value, binds circles and text, and positions them with a vertical spacing transform. A `scaleOrdinal` maps the domain to a color range, with the legend called via `selection.call()`. The SVG rendering applies styled ticks and circle strokes from an external stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
