{"version":"1.0","type":"rich","title":"task 3.2","description":"This example shows a scatter plot of the Iris dataset, with sepal length mapped to the x-axis, petal length to the y-axis, and species distinguished by different symbol shapes. A custom shape legend labels each species group. The visualization loads CSV data via `d3.csvParse` and uses D3 v7’s `scaleLinear`, `scaleOrdinal`, `symbol`, `symbolsFill`, and axis functions (`axisLeft`, `axisBottom`) to render marks and axes. A local ES6 module structure organizes the code into separate files for the chart, axes, and legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f43919f7d3f042ba820496c708908566?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
