{"version":"1.0","type":"rich","title":"Task 4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s x-position maps to horsepower, y-position to torque, and its radius encodes highway MPG, while color distinguishes the manufacturer.  \n\nRendered as SVG with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with an interpolated turbo color palette for categories, and a custom tooltip on mouseover. Animated hover effects and a dual legend for MPG values and color categories are included. The data comes from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41f6b3a649f84eb1b572940dc73c64af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
