{"version":"1.0","type":"rich","title":"Activity6_Task4(Tutorial)","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s x-position maps to horsepower, its y-position to torque, and its radius to highway MPG, while its color encodes the car manufacturer. The visualization is built with D3.js v7, loading data from a local CSV via `d3.csv`. Interactive tooltips appear on hover, showing the make of each car. The chart also includes a legend for the bubble-size scale and a categorical color legend, all rendered as SVG with animated transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff4f8991dac94a0bad8e4c6e9deed37a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
