{"version":"1.0","type":"rich","title":"Activity6_Q2","description":"This stacked bar chart compares car performance by manufacturer, breaking down horsepower, torque, and highway MPG into color-coded segments along a horizontal axis. It loads CSV data via D3 v7, uses `d3.stack()`, `d3.scaleBand()`, `d3.scaleLinear()`, and `d3.axisBottom()` to render SVG bars, and includes interactive tooltips on mouseover for metric values. A legend maps the three metrics to distinct colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee9c2f705e9541d49e5c0250ca5052fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
