{"version":"1.0","type":"rich","title":"Bowl of Fruit - General Update Pattern Special Cases","description":"This example demonstrates two reusable legend components, a color legend and a size legend, built on the general update pattern. The color legend maps fruit names to ordinal colors, while the size legend uses a square-root scale to represent numeric values through circle radii. Both legends handle enter, update, and exit selections via `selection.merge` and `selection.exit().remove()`. The code uses d3.scaleOrdinal, d3.scaleSqrt, and explicit SVG rendering with appended `circle` and `text` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4111899fcd44ec7ab78657ddc2cd0a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
