{"version":"1.0","type":"rich","title":"Acticity 7 tutorial2","description":"This example shows a stacked bar chart comparing average horsepower, torque, and highway MPG for several car makes, using an ordinal color scale and a legend to distinguish the three metrics. It renders the chart as an SVG and relies on D3.js version 7 APIs including `d3.stack` for data stacking, `d3.scaleBand` for categorical positioning, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` with rotated labels to handle long axis text. The data is embedded directly in the script rather than loaded from an external file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd9697699fee4ab8afe53e8b7139f63f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
