{"version":"1.0","type":"rich","title":"activity6_tutorial","description":"This example presents an interactive scatter plot of Fisher’s Iris dataset, visualizing sepal length against petal length with point shapes distinguishing the three species. Built with D3 v7, it uses `d3.scaleLinear` for the axes, `d3.scaleOrdinal` with `symbolsFill` to encode species as distinct symbols, and custom modules `axes.js` and `shapeLegend.js` to generate a labeled legend. Data is fetched as CSV and parsed with `d3.csvParse`, with numeric fields coerced before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/da056e17161d4533a43117af225a9a4e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
