{"version":"1.0","type":"rich","title":"Color and Size Legend","description":"Two reusable D3 legend components render side by side in an SVG: a color legend for a categorical scale (scaleOrdinal with apple, lemon, orange, kiwi) and a size legend for a square-root scale (scaleSqrt for 0–10). Each legend positions circles and text with data-driven transforms, and the size legend filters out zero ticks and uses D3’s `ticks()` to generate intervals. The React-wrapped code updates selections via enter/merge/exit patterns, with styling from external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/46c11dcde9504072a95aeda1ed78db97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
