{"version":"1.0","type":"rich","title":"activity-6_question-4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various vehicle makes. Each circle’s position on the x- and y-axes corresponds to its horsepower and torque values, while its radius encodes highway MPG, and its color distinguishes the make. Built with D3.js (v7), the chart uses `d3.scaleLinear` for axes and size, `d3.scaleOrdinal` with `interpolateTurbo` for color, and SVG circles with an interactive tooltip that displays the make on hover. Data comes from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc5929c6f6fc44d29c8d29fe0087ad0b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
