{"version":"1.0","type":"rich","title":"Lollipop Chart USA Flights On-time Performance","description":"A lollipop chart visualizes USA flight on-time performance by day of the month, comparing average departure delay (green circles) against arrival delay (purple circles) for each day. The chart uses D3 v4’s `scaleLinear` for the horizontal delay axis and `scaleBand` for the vertical day axis, with lines connecting the two delay values per day. Data is loaded from a CSV via `d3.csv` and rendered as SVG circles and lines within a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71cecd997f2a4473abbd42a18570310e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
