{"version":"1.0","type":"rich","title":"Fork of Activity6_Task2 sample","description":"A stacked bar chart visualizes Iris dataset measurements across four numeric variables—sepal length, sepal width, petal length, and petal width—grouped by species. Each horizontal bar shows the cumulative measurement values, with segments colored by variable. Hovering over a segment highlights it and displays the exact measurement value via a tooltip.\n\nThe visualization uses D3 v7 with SVG rendering. It employs `d3.stack()` for data stacking, `d3.scaleOrdinal()` for colors, and `d3.scaleBand()` for the categorical species axis. Interactive tooltips are implemented using mouse event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/625642b1e5304894900eff9f6aa23b07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
