{"version":"1.0","type":"rich","title":"Yearly Region-Wise Air Passenger Heatmap","description":"This heatmap visualization displays the total air passenger counts for various global regions across time, from 2005 to 2019. It aggregates the data by region and year, using a Viridis color scale to encode the passenger volumes. The visualization is rendered as an SVG graphic using D3.js v5, with axes for years and regions. It relies on D3’s scale functions and a nested data grouping API to structure the dataset, sourced from DataSF’s Air Traffic Passenger Statistics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fcaacbefafb442a69b9df76b5ded31a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
