{"version":"1.0","type":"rich","title":"Fork of Interactive Color Legend","description":"This example visualizes the Iris Dataset with a scatter plot of sepal length against petal length, coloring each point by species. An interactive color legend lists the three species; hovering over a legend entry highlights the corresponding marks by adjusting their opacity, while dimming the rest. The chart uses D3 v7 APIs including `scaleOrdinal`, `schemeCategory10`, `selection.join`, and event handlers for mouseover and mouseout. Data is loaded asynchronously from a CSV and parsed with `csvParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/324518bcfbe54e9b8327b67c178b5528?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
