{"version":"1.0","type":"rich","title":"Activity6_Tutorial3.1","description":"This example visualizes the Iris dataset with a scatter plot, mapping petal length and petal width on the x- and y-axes while coloring each point by species (setosa, versicolor, virginica). The SVG rendering uses D3 v6’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to position and label the axes, with circles sized at a fixed radius. Data is loaded asynchronously via `d3.csv` from a GitHub raw URL, and each mark’s fill color is assigned through a custom switch statement. Axis labels are added as SVG text elements with rotated and centered styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72d169430a30455c8cddc5b3ea65c349?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
