{"version":"1.0","type":"rich","title":"Tutorial3.1_Activity6","description":"This example shows a scatter plot of the Iris dataset, mapping sepal length to the x-axis and petal length to the y-axis, with species indicated by point shape. The visualization uses a categorical color-free shape legend to identify the three species, with axes labeled by the corresponding measurement variables. Built with D3 v7, the code leverages `scaleLinear`, `scaleOrdinal`, `symbol`, and `axisLeft`/`axisBottom` from the `d3` module, while fetching and parsing the CSV data via `csvParse`. The rendering uses a custom `scatterPlot` function that joins SVG path elements with `symbolsFill` shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/013da3f4e5d74ab494211e2d94311497?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
