{"version":"1.0","type":"rich","title":"Iris data set","description":"This visualization compares average sepal and petal lengths across the three Iris species using a combined bar and line chart. Blue bars represent average sepal length, while an orange line with dots tracks average petal length per species. The code aggregates the Iris dataset with `d3.groups` and `d3.mean`, then renders the chart with D3 v7 using `d3.scaleBand`, `d3.scaleLinear`, and `d3.curveMonotoneX`. A custom legend and labeled axes clarify the dual encodings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fff2ccf9434b47c085c332dd4a9ea4bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
