{"version":"1.0","type":"rich","title":"tutorial 3.2","description":"This example shows an interactive scatter plot of the Iris dataset, comparing sepal length against petal length, with each of the three species distinguished by a unique symbol shape via a custom legend. The visualization is built with D3 v7, using `d3.scaleLinear` for axes, `d3.scaleOrdinal` and `d3.symbolsFill` to map species to symbols, and `d3.csvParse` to load and parse the remote CSV data. Custom modules handle axis rendering and legend construction, with the chart filling the entire viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/356b654b0191448d8388f6c449b75951?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
