{"version":"1.0","type":"rich","title":"act6_shapeplot","description":"This example visualizes the Iris dataset by plotting sepal length against petal length, with each of the three iris species distinguished by a different symbol shape. The scatter plot uses D3 v7’s `scaleLinear`, `scaleOrdinal`, and `symbol` APIs to position points and generate the distinct marker shapes, while a custom shape legend explains the species mapping. The chart is built with reusable D3 modules for scatter plot rendering, axes, and legend, and it loads data via `fetch` and `csvParse` from a raw GitHub CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac5259aa368547dfb9b1866846d10793?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
