{"version":"1.0","type":"rich","title":"USA airlines on-time performance","description":"This line chart displays the average departure delay for USA airlines over time, with each date point visualized as a circle and connected by a smooth natural curve. The visualization uses React to render SVG elements and D3 v5 scales, including `scaleTime` for the date axis and `scaleLinear` for delay values. Data is loaded asynchronously from a CSV file containing daily mean departure delays, and the chart includes labeled axes, grid lines, and interactive tooltips showing formatted dates on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d486c0b0ac2f43658eca7418f890d68c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
