{"version":"1.0","type":"rich","title":"Comparing '70s Cars' Weight vs MPG. [An Interaction Design by Hails].","description":"This visualization compares the weight and miles-per-gallon of 1970s automobiles, with each car represented as a circle colored by its model year. It is built using the vega-lite-api, which wraps vega-lite in JavaScript, and the resulting chart renders as SVG via vega’s renderer. The code loads data asynchronously with d3.csv, then encodes the x-position from the quantitative Weight field, the y-position from MPG, and uses a nominal color scale for Year. Tooltips display each car’s name via the vega-tooltip Handler, with custom font sizing in the config for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5362bfafbf2c4e2a9c5c0b4409a1329f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
