{"version":"1.0","type":"rich","title":"Activity6_task4","description":"A bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position maps to horsepower (x-axis) and torque (y-axis), while its radius and color encode highway MPG and make, respectively. The visualization uses D3.js v7 to render SVG circles, with a tooltip on hover and a legend for MPG scaling and make colors. Data comes from bubblechart.csv, processed through d3.csv and d3.scaleOrdinal. The chart includes silver axes via d3-axisLinear and uses d3.interpolateTurbo for color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63ea3ec8a0c34ea4a452cff8a412c5ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
