This choropleth map visualizes international tourist arrivals worldwide, showing the latest available year’s values per country through a red sequential color scale. It employs D3.js v7 with a GeoNaturalEarth1 projection and TopoJSON world geometry, joining tourism data from Our World in Data via ISO-3 country codes. Hovering reveals a tooltip with country name and arrival count. The visualization uses d3.geoPath for rendering, d3.scaleSequential for color mapping, and a graticule layer for geographic context.
