{"version":"1.0","type":"rich","title":"Activity 6_task 4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across various car makes, with each circle's position representing horsepower and torque, its size encoding MPG, and its color distinguishing the manufacturer. Built with D3 v7, the visualization uses scales like `d3.scaleLinear` for axes and bubble radius, and `d3.scaleOrdinal` with an interpolated Turbo colormap for categorical colors. Interactive tooltips appear on mouseover, and a legend displays both the MPG size scale and color categories. Data comes from the `bubblechart.csv` file, rendered as SVG elements with animated opacity transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8f26bc1d5844624965d5c51b596aa22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
