This fork of a simple world map displays country boundaries through a Natural Earth projection, with a graticule overlay and outlined map edges. The visualization fetches geospatial data from the `visionscarto-world-atlas` package, converts it using `topojson.feature`, and renders it via `d3.geoPath` and projection functions. The code employs the `select` and `join` operations from the D3 API to manage SVG paths, styling countries with white strokes and a fine graticule grid. The map fills the full browser window and updates dynamically once the topological data loads.
