{"version":"1.0","type":"rich","title":"HW6 — Year Comparison","description":"This interactive D3.js visualization compares simulated car fuel efficiency (MPG) across years 2019–2024, using engine size and vehicle type as axes and color categories. It offers two views: an animated year-by-year transition and a side-by-side small multiples comparison, synchronized with a timed trial feature. The chart uses `d3.csv` to load data, `d3.scaleOrdinal` for color mapping, and SVG rendering with buttons for animation playback and timing. Both views share identical axis ranges and vehicle-type colors, helping users identify upward shifts in MPG for vehicle categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2563dab224324dbeac229f5879b04a37?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
