{"version":"1.0","type":"rich","title":"activity6_tutorial3.2","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 points colored by shape according to species. A custom legend shows the shape-to-species mapping. The visualization uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol` to generate the point glyphs, while `axisLeft` and `axisBottom` render the axes. Data is loaded asynchronously via `fetch` from a GitHub-hosted CSV file and parsed with `csvParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7507f59396e44bb8ac37b3cc03bb394f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
