{"version":"1.0","type":"rich","title":" Activity6_Task4 question","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for a dataset of fictional car makes. Each circle's x-position maps to horsepower, its y-position to torque, and its radius to highway MPG. Color encodes the car make, with a legend showing the MPG scale and color categories. The visualization uses D3.js v7 with `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, `d3.scaleOrdinal`, and `d3.interpolateTurbo` for color assignment. Animated opacity changes and a custom tooltip appear on hover via D3 transitions, with the SVG rendered directly from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f3746683750d491ba137573da325a7dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
