{"version":"1.0","type":"rich","title":"Activity6_tutorial3.2","description":"This scatter plot shows the relationship between sepal length and petal length for Iris flowers, with each species represented by a distinct shape in a custom legend. The visualization uses D3 v7's `scaleLinear` and `scaleOrdinal` to map measurements and categorical species, while the `symbol()` generator draws the shape marks. Data is loaded from a remote CSV file via `fetch` and `csvParse`, then parsed into numeric fields. Axes and labels are created using custom `axisLeft` and `axisBottom` functions from D3's `d3` module, and the shape legend is built dynamically with positioned `path` and `text` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/78a2ddc8f14a49b7a950c98744c12125?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
