{"version":"1.0","type":"rich","title":"Interactive Color Legend","description":"This interactive scatterplot visualizes Iris flower measurements, plotting sepal length against sepal width for three species. The React-based interface uses D3.js scales (scaleLinear, scaleOrdinal) to position and color each circle. A custom ColorLegend component responds to mouse hover events, highlighting the selected species by fading all other points to 20% opacity. Hovering a legend item filters the visible marks, while tooltips display exact values. Data loads asynchronously from a CSV file using d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36068dba36d44462b2fbb762842e3cb3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
