{"version":"1.0","type":"rich","title":"Activity8_Task2_DV_LB_Q2.1","description":"This stacked bar chart displays the efficiency of fourteen car makes by comparing their average horsepower, torque, and highway MPG values. The visualization uses D3.js version 7 to implement a horizontal stacked bar layout, where each make is a row and the three metrics are stacked segments. The data is loaded from a CSV file and processed with the `d3.stack()` API to create the cumulative bars. The chart includes interactive tooltips that display the exact numeric value for each metric segment when hovered, and uses a custom color scale to distinguish between the three efficiency metrics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f18f488b17b40438d73c594878cd9bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
