{"version":"1.0","type":"rich","title":"airtraffic dashboard","description":"This dashboard presents twelve interactive views of air traffic data, including a year-by-month passenger heatmap with a `d3.scaleSequential` Turbo color scale, an airline performance bar chart with tooltips, and trend, CO₂, and correlation analyses. Each chart is toggled via buttons that control CSS `display`. The visualizations use D3 v7 to fetch a CSV from a GitHub gist and render SVGs with `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleBand`/`d3.scaleLinear`, styled with a dark cyan-on-black theme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ef8cc26a26b40bc92f0496e6344cc73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
