{"version":"1.0","type":"rich","title":"question 2","description":"This example displays petal length distribution across iris species using a stacked area chart. It loads data from a remote CSV file and renders an SVG visualization. The code imports D3 functions including `csv`, `scaleBand`, `scaleLinear`, `stack`, and `area`. It constructs an area generator with band scale positioning, adds axes via `axisBottom` and `axisLeft`, and labels the chart with a title. The visualization shows how petal lengths vary among species, with steelblue filling for the area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27448e608e5045cf849f56341b6dc64e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
