{"version":"1.0","type":"rich","title":"Bubble chart","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its radius represents highway MPG and its color maps to the car manufacturer. Built with D3 v7 and SVG, the chart includes interactive tooltips on mouseover, a size legend, and a color legend. Data is loaded from a remote CSV using `d3.csv`, with scales created via `d3.scaleLinear` and `d3.scaleOrdinal`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/453ed04bd67c47f2832bb00eaa0f430b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
