{"version":"1.0","type":"rich","title":"A Map for USA Airport","description":"This map visualization displays the distribution of airports across the United States, with each circle representing an airport positioned by its latitude and longitude, colored by state, and showing the airport name on hover. Built with vega-lite-api, it uses the `vl.markCircle` method with latitude and longitude encoding streams to project the geographic data points. The code loads airport information from a CSV file using d3.csv, applies custom axis and label styling through a shared config object, and renders the final chart with vega and vega-lite in an SVG view.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f4473df596c4e2084e0ccf651fa74ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
