{"version":"1.0","type":"rich","title":"Task 8_tutorial3.2","description":"This scatter plot visualizes the Iris dataset, comparing sepal length against petal length for different iris species. The chart encodes each data point as a distinct shape, using the `d3.symbol` API with a `symbolsFill` scale to differentiate species, and includes a shape legend generated via `shapeLegend`. The visualization uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` for species mapping, with custom axis and legend utilities built on D3's selection join pattern. Data is fetched as CSV from a GitHub repository and parsed with `d3.csvParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/142e426a154c407cbd6303fe86dbaeb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
