{"version":"1.0","type":"rich","title":"activity6_tutorial3.1","description":"This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes while encoding species with distinct colors. The D3 v6 code loads CSV data from a GitHub repository, then uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to create the chart. Circles are drawn via `svg.selectAll('circle').data(marks).join('circle')` for each observation. Axis labels appear in green, and the plot fills the browser window, with a legend implied by the color mapping for setosa, versicolor, and virginica species.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fb659c1a8db43e89334a431a251b369?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
