{"version":"1.0","type":"rich","title":"Fork of A7-Multi-Line Chart in D3","description":"This multi-line chart displays monthly flight delay counts for four delay categories—carrier, late aircraft, national aviation system, and weather—across airports. It loads CSV data from a GitHub gist using `d3.csv`, then renders paths via `d3.line` with a `d3.scaleBand` x-axis and `d3.scaleLinear` y-axis. Color-coded lines and a manual legend distinguish categories, while axes are generated with `d3.axisBottom` and `d3.axisLeft`. The SVG output uses D3 v6 with the d3-legend library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8fdf94bfe4564cc2af3051f3cc38e8af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
