{"version":"1.0","type":"rich","title":"Activity 6_Task4 ","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, using data from bubblechart.csv. The visualization encodes torque on the y-axis, horsepower on the x-axis, and highway MPG through both bubble size and color, with a color legend for car makes and a size legend for MPG values. The code uses D3 v7 with SVG rendering, employing scales (d3.scaleLinear, d3.scaleOrdinal) and interactive tooltips that respond to mouse events, with animated opacity transitions on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58541e6adaeb4f42a58606f394fea490?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
