{"version":"1.0","type":"rich","title":"act8_task4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position maps horsepower on the x-axis and torque on the y-axis, while circle radius encodes highway MPG and color distinguishes make. The visualization uses D3 v7 with SVG rendering, including a tooltip on mouseover, a legend for bubble size, and color-coded dots. Data is loaded from a CSV file and mapped through d3.scaleLinear and d3.scaleOrdinal scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56d46c8025e14fb68ebadc79bb84fed4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
