{"version":"1.0","type":"rich","title":"Task8_Tutorial4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s x-position maps to horsepower, y-position to torque, and its radius encodes highway MPG, while color distinguishes the brand. The chart includes a legend for bubble size and a tooltip that appears on mouseover, implemented with d3.v7 and SVG. Data is loaded from a CSV file, and scales such as d3.scaleLinear and d3.scaleOrdinal handle the visual mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/906c9a8ea0ca47f59208d7e325897b82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
