{"version":"1.0","type":"rich","title":"Activity3Tutorial3.2","description":"This example visualizes the iris dataset as a scatter plot, mapping sepal length to the x-axis and petal length to the y-axis, with each species represented by a distinct shape from D3’s `symbolsFill` array. A legend built with the `shapeLegend` module identifies the species symbols.\n\nThe code uses D3 v7 (`d3.scaleLinear`, `d3.scaleOrdinal`, `d3.extent`, `d3.symbol`) to construct scales and generate marks via the `symbolGenerator`. Data is fetched as CSV from GitHub, parsed with `d3.csvParse`, and rendered responsively to the full window size. The axes and labels are drawn through a reusable `axes` module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e1e4e0672fe49f98a78ecfae6d928d0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
