{"version":"1.0","type":"rich","title":"Activity 7.1 question 2","description":"This example visualizes the distribution of petal length across iris species using a stacked area chart. It loads CSV data from a GitHub gist via D3’s `csv` method, then applies `scaleBand` for species categories and `scaleLinear` for petal length values. The chart uses `stack` and `area` generators to render a single filled area, with `axisBottom` and `axisLeft` for axes, and a title annotation. SVG output is produced through D3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/73cf45f46e9345b986a426a374e77df7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
