{"version":"1.0","type":"rich","title":"Bowl of Fruit - General Update Pattern Special Cases","description":"Two custom legends demonstrate the general update pattern under special cases using D3 v5. The color legend maps fruit names to ordinal colors, while the size legend uses a square-root scale for circle radii. Both legends are built with reusable modules that leverage selection joins, enter/merge/exit methods, and explicit spacing. The code uses d3.scaleOrdinal, d3.scaleSqrt, and the .call() method to attach the legends to an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b761a06fd17a41d5ab87fbb102c84897?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
