{"version":"1.0","type":"rich","title":"tutorial3.2","description":"This example demonstrates a scatter plot of the Iris dataset, showing sepal length versus petal length, with species encoded by symbol shapes and a corresponding shape legend. The visualization uses D3 v7 APIs including `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.symbol`, `d3.axisLeft`, and `d3.axisBottom`. Data is loaded asynchronously as CSV and parsed with `d3.csvParse`. The code is modularized into separate ES6 modules for the scatter plot, axes, and legend, built as a reusable visualization component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/795bd71539c241df8eae8f2878cbaa0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
