{"version":"1.0","type":"rich","title":"Activity_6 Tutorial 4","description":"This bubble chart visualizes the relationship between horsepower, torque, and highway fuel efficiency across 31 car makes. Each circle’s x-position represents horsepower, y-position represents torque, and its radius encodes highway MPG values. The visualization uses D3 v7 to create SVG elements, employing `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble sizing, and `d3.schemeTableau10` extended with additional palettes for color encoding. Data is sourced from a CSV file containing make, horsepower, torque, and highway_mpg statistics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bc52e66c498447aae5deee836f7ffed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
