{"version":"1.0","type":"rich","title":"Activity-6_Question-4","description":"This animated scatterplot uses D3.js (v7) to show the correlation between price, weight, and city MPG across 43 car makes. Each circle’s x-axis position maps to price, y-axis to weight, and radius encodes fuel efficiency values read from `bubblechart.csv`. D3’s `scaleLinear`, `scaleOrdinal`, and `d3.interpolateTurbo` assign color per make, while mouse events trigger a styled tooltip with make-specific details. A legend with outlined bubbles and dashed lines clarifies MPG size encoding using SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/661cde982bc2410da8b8e53fac11bb75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
