{"version":"1.0","type":"rich","title":"Fork of  Flight Map","description":"This visualization presents a world map with animated flight paths between continents, using a Mercator projection created with `d3.geoMercator()`. The map is rendered as SVG paths via `d3.geoPath()`, with each intercontinental link colored differently and its stroke width proportional to monthly passenger counts. A slider allows users to select a month (1–12), updating the path widths accordingly from CSV data files. Hovering over a path reveals its exact value via a tooltip, and the map itself uses `d3.json()` to load world GeoJSON data. The code relies on D3 v4 APIs including `d3.select`, `d3.transition`, and `d3.event` for interaction, with styling applied through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1180368270ac41d09b6a533d32be55df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
