{"version":"1.0","type":"rich","title":"Activity6_Task4_Question4","description":"This interactive bubble chart from VizHub visualizes the correlation between car horsepower, MPG, and weight using data from a local cars.csv file. Each bubble’s x-position maps to horsepower, y-position to MPG, and radius to vehicle weight, rendered as SVG circles with tooltips. Built with D3 v7, it uses `d3.scaleLinear` for axes and bubble sizing, `d3.axisBottom` and `d3.axisLeft` for scales, and mouse event handlers for the tooltip. The chart animates opacity changes on hover, with black stroke outlines and skyblue fills.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a50c4bfd8a84526a4043a6449e4f102?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
