{"version":"1.0","type":"rich","title":"tutorial 3.2","description":"This example visualizes the classic Iris dataset, plotting sepal length along the x-axis and petal length along the y-axis for individual flowers. Each data point is represented by a distinct shape corresponding to its species, with a legend showing the species-to-shape mapping. The code builds the scatter plot using d3’s `scaleLinear` and `scaleOrdinal` scales, and renders points via `symbol` generators. Axes are added using `axisLeft` and `axisBottom`, while the shape legend is constructed manually with `symbol` and text elements. Data is loaded asynchronously via `fetch` from a remote CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/afc3a1b53e6744a6b72b97e3b197e3b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
