{"version":"1.0","type":"rich","title":"Color and Size Legends","description":"This example demonstrates two distinct legend types rendered side by side in SVG. A color legend uses `d3.scaleOrdinal` to map fruit categories—apple, lemon, lime, and orange—to distinct hues, with each entry displayed as a filled circle and label. A size legend uses `d3.scaleSqrt` to encode a numeric domain from 0 to 10 through varying circle radii, generating tick values via `sizeScale.ticks`. Both legends are constructed with reusable D3 functions that bind data to groups, updating circle and text elements on enter and merge.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12b6df18b5074bb7af5cf54ea3a2edde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
