{"version":"1.0","type":"rich","title":"Activity6_Tutorial3.2","description":"This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length for three species of iris flowers. Each species is distinguished by a unique symbol shape: circles for setosa, squares for versicolor, and triangles for virginica, with a custom legend generated by the `shapeLegend` function. The chart uses D3 v7’s `scaleOrdinal`, `scaleLinear`, and `d3.symbol` to render SVG marks, along with axes created via `d3.axisBottom` and `d3.axisLeft`. The data is loaded from a CSV file and mapped to numeric values before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15d0c4d2010b4367be53f293ff419944?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
