{"version":"1.0","type":"rich","title":"Tutorial_3.2","description":"This example demonstrates a D3.js scatter plot of the Iris dataset, showing sepal length against petal length with species encoded by symbol shapes. It uses D3 modules like `csvParse`, `scaleLinear`, `scaleOrdinal`, `schemeCategory10`, and `symbol` to render the marks. It also includes custom axes and a shape legend built with `axisLeft`, `axisBottom`, and `symbolGenerator`. Data is fetched from a CSV file via UNPKG and processed into numeric fields before visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dabf33120a14934a4c99b09f87bec41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
