{"version":"1.0","type":"rich","title":"A2Q4","description":"This example visualizes the classic Iris dataset with a scatter plot comparing petal length on the x-axis against sepal length on the y-axis. Each point represents a flower sample, colored by species (setosa, versicolor, or virginica) via CSS classes. The code uses D3 v7’s `csv`, `scaleLinear`, `extent`, and `axisLeft`/`axisBottom` to load the data, map values to screen coordinates, and render axes. SVG circles are joined with data using the `join` method, producing a clear taxonomic distribution.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/198b21cb0ab04a5d9163df3b9277fccb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
