{"version":"1.0","type":"rich","title":"A7 Heat Map","description":"This heat map visualizes airline carrier delays across months and years, using a blue sequential color scale to show delay frequency. The SVG visualization is built with D3 v7, positioning cells via `d3.scaleBand` for the x-axis (months) and y-axis (years), while `d3.scaleLinear` maps delay counts to color intensity. Interactive tooltips appear on mouseover, and a legend is generated using the d3-legend library. Data comes from a CSV file of filtered airline statistics hosted on GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0fbc235c4d6b4a14a9a71ceb1cd48c01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
