{"version":"1.0","type":"rich","title":"Activity 6_task4","description":"This interactive bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across 31 car makes, with each bubble representing a make. The chart plots horsepower on the x-axis and torque on the y-axis, while bubble size encodes highway MPG and color distinguishes car brands. Built with D3 v7, the visualization includes an SVG-based tooltip that displays the make name on mouseover, along with a size legend for MPG values and color legend for brands. Data comes from a CSV file, and the tooltip responds to mouse events for interactive exploration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d1f9ae448ea4754be436cd2ff09e076?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
