{"version":"1.0","type":"rich","title":"Activity - 6_Question - 2.3","description":"This stacked bar chart displays the average sepal and petal measurements for iris species from the provided CSV dataset. The visualization aggregates the raw data using `d3.nest()` and `d3.rollup()` to compute means per species, then renders four stacked segments per species using `d3.stack()`. Each segment’s height corresponds to its average measurement, with colors assigned via `d3.scaleOrdinal(d3.schemeCategory10)`. The chart uses D3 v5 with an SVG rendering approach, including axes generated through `d3.axisBottom()` and `d3.axisLeft()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10fe9587ce4e487da2e8b7e3e109cec5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
