{"version":"1.0","type":"rich","title":"Activity6_tutorial4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each circle’s position encoding horsepower on the x-axis and torque on the y-axis, while radius and color represent MPG and make, respectively. Using d3.v7, the chart loads data from a CSV, renders SVG circles with tooltips on hover, and includes a legend for circle size and color. Interactive features rely on event handlers for mouseover, mousemove, and mouseleave to display tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/07939755a40c4b41af80396ab77cca93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
