{"version":"1.0","type":"rich","title":"Fork of Question 4: Multi-Series Chart (Bar + Line)","description":"This fork of “Question 4” presents two SVG charts built with D3 v7. The first is a multi-series line chart with circular markers, displaying average sepal and petal measurements for three Iris species. The second is a combined bar-and-line chart that juxtaposes the same aggregated data, using the `d3.scalePoint` and `d3.scaleLinear` APIs for positioning. Gridlines, axes, legends, and a title are generated with D3’s `axisBottom` and `axisLeft` methods, while smooth lines use `d3.curveMonotoneX`. The data consists of precomputed averages from the Iris dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95c4a7b9710e4f7f98b6dc0f52122514?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
