{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive bubble chart visualizes the relationship between engine horsepower, torque, and highway fuel efficiency for various vehicle makes. Each bubble is positioned along the x-axis by horsepower and the y-axis by torque, while its radius encodes highway MPG. The chart uses D3.js v7 with the `d3.csv` method to load data from bubblechart.csv, `d3.scaleLinear` for axes and bubble sizing, and `d3.schemeTableau10` for categorical color coding. Hovering over a bubble triggers a tooltip displaying exact values, with SVG circles providing the animated visual representation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86e7c496b0a64792a1fb90f3339fac1b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
