{"version":"1.0","type":"rich","title":"Assignment 5 - Scatterplot matrix","description":"This visualization combines a scatterplot matrix of car attributes with a bubble chart comparing average horsepower, torque, and highway MPG by brand. The matrix displays pairwise relationships among six numeric variables, with each point colored by car make using `d3.scaleOrdinal` and `d3.interpolateTurbo`. The bubble chart encodes highway MPG through circle radius via `d3.scaleLinear`, with a tooltip implemented using D3’s event handlers. Both views use `d3.csv` to load data and D3 v7 to render SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9deb34dd140d4324bdd985e1a6c1f028?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
