{"version":"1.0","type":"rich","title":"Color and Size Legends","description":"Four ordinary categorical color swatches form a simple legend for fruit types. Each circle is rendered with a distinct fill from an ordinal color scale, and its label appears below it. The example demonstrates how to build a reusable legend component by binding the color scale’s domain to SVG circles and text elements.
