{"version":"1.0","type":"rich","title":"Activity6_Q2","description":"A stacked bar chart compares car makes by three metrics: horsepower, torque, and highway MPG. Each horizontal bar is segmented by metric, with a color scale distinguishing them and a legend implied by the colors. The visualization loads CSV data via `d3.csv` and uses `d3.stack`, `d3.scaleOrdinal`, `d3.scaleLinear`, and `d3.scaleBand` to construct the SVG rendering. Interactive tooltips display the metric value on hover, using mouse events and a styled div.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fb18fc48d2a541cb906e1e58abbb4b8d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
