{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car brands. Each circle’s x-position maps to max speed, y-position to acceleration, and size to fuel efficiency, while color encodes the brand. The D3 v7 code (with SVG) uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `interpolateTurbo` for colors, and interactive tooltips on mouseover. A legend shows MPG values and brand colors, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd153e95b8ed473c9f4a85b051e7d78a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
