{"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 scales with highway MPG and its color maps to the car make. Built with D3.js v7, it renders as SVG with interactive tooltips on hover and includes a bubble-size legend and color-coded make identifiers. Data is loaded from a CSV file and processed using `d3.csv`, with scales and axes created via `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d067ee924a44fe2ab885c65c7b91b8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
