{"version":"1.0","type":"rich","title":"Activity-6_Tutorial-4","description":"This interactive bubble chart visualizes correlations between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position encodes horsepower and torque, while its radius represents highway MPG and color distinguishes the manufacturer. Built with D3 v7, the visualization renders SVG elements and includes an interactive tooltip on hover. The code uses d3.scaleLinear, d3.scaleOrdinal, and d3.interpolateTurbo for color mapping. Data is loaded from the included bubblechart.csv file, with axis labels and a legend for bubble sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0bdf48c6bb4f44048693c3626e1667f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
