{"version":"1.0","type":"rich","title":"activity7_question2","description":"This stacked area chart visualizes the distribution of sepal width, petal length, and petal width across different sepal length values, using the classic Iris dataset. The chart shows how these three flower measurements contribute proportionally to the total across the range of sepal lengths, with color-coded categories shown in a legend. The visualization is built with D3.js (v7) and renders as an SVG, using `d3.stack()` for the stacked data, `d3.area()` for the area path generation, and `d3.scaleOrdinal()` for color mapping. The code reads data from a local CSV file and includes custom styling with fonts from Google Fonts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d045764a0f7e4821b7fe9e77214d1315?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
