{"version":"1.0","type":"rich","title":"task 3.2","description":"This example displays a scatter plot of the Iris dataset, plotting sepal length against petal length. Points are colored and shaped according to species, with a custom legend identifying each species by its unique symbol. The visualization uses D3.js (v7) to fetch and parse the CSV data from a GitHub repository, then renders the plot within an SVG. It constructs axis scales with `scaleLinear`, applies shape encodings through `scaleOrdinal` and `symbolsFill`, and generates marks via `symbolGenerator`, with axes and legends created by custom functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69b6f9f4b52d46b8880c0d08b9c4141f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
