{"version":"1.0","type":"rich","title":"Tutorial_4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while the radius maps to highway MPG and color distinguishes car make. Built with D3.js (v7), the visualization includes hover tooltips, a legend for MPG values, and a color legend for makes. Data is loaded from a CSV file, rendered as SVG, and scales are defined using `d3.scaleLinear` and `d3.scaleOrdinal`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/022a2805f5fe481e8ad58e5d03566434?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
