{"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 circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius scales with highway MPG and its color distinguishes the make. The visualization includes interactive tooltips on hover, plus legends for bubble size and color categories. It loads data from a CSV file and uses D3 v7 scaleLinear, scaleOrdinal, axisBottom, axisLeft, and event handlers. The chart is rendered as SVG with animated opacity transitions on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/181dc4c26baf4a18a31806debd490859?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
