{"version":"1.0","type":"rich","title":"Color and Size Legends","description":"This example demonstrates two distinct legend types for different data encodings: a color legend with categorical swatches for fruits and a size legend with scaled circles for numeric values. Built with D3 v5, it renders SVG elements using reusable functions `colorLegend` and `sizeLegend`. The color legend uses `scaleOrdinal` with discrete colors, while the size legend employs `scaleSqrt` and generates ticks via `sizeScale.ticks()`. Both legends position circles and text labels with explicit spacing and offset values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/122b92d81fce4bf583dc216413b0edba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
