{"version":"1.0","type":"rich","title":"Activity6_tutorial3.2","description":"This example shows a scatter plot of the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis. Each point is rendered as a different shape (circle, square, triangle, etc.) based on the iris species, with a legend explaining the shape-to-species mapping. The visualization uses D3 v7’s `scaleLinear`, `scaleOrdinal`, and `symbol` APIs to position marks and generate custom path shapes. Data is loaded as CSV from a GitHub repository and parsed with `csvParse`, while axis and legend components are built using `axisLeft`, `axisBottom`, and reusable selection patterns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dd69db753e34f2ba869f7ff0b780250?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
