{"version":"1.0","type":"rich","title":"Color and Size Legends","description":"This example demonstrates how to create custom legends for both ordinal color scales and continuous size scales in D3 v5. It shows a color legend with four fruit categories (apple, lemon, lime, orange) rendered as colored circles, and a separate size legend with scaled circles representing values from 0 to 10. The code builds reusable legend components using D3’s `scaleOrdinal`, `scaleSqrt`, and `selection.call()`, rendering everything as SVG elements with styled fonts and circle strokes defined in CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59e9349cc10848d8bd35f49ac6aafdb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
