{"version":"1.0","type":"rich","title":"Scatter Plot with Color and Size","description":"This scatter plot visualizes the Iris dataset, displaying petal length and width on the x- and y-axes while encoding sepal length through point size and species through color. The D3 v7 code uses `d3.csv` with `d3.autoType` to load data, then `d3.scaleLinear` for axes, `d3.scaleOrdinal` for categorical colors, and `d3.scaleSqrt` to map a third continuous variable to circle radius. Hover tooltips provide exact values for all four measurements per flower.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3044ff0c09324bf5a8fa7008c5f2caf6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
