## What it is
A redistribution of Natural Earth vector data as pre-built TopoJSON files at 1:110m, 1:50m, and 1:10m scales, containing country and land geometries. It is designed for use with d3-geo to render world maps in browsers or Node.

## Use cases
- render a world map with d3-geo
- get country boundary polygons as TopoJSON
- draw choropleth maps of countries
- add a land layer to a data visualization
- download lightweight world geometry for web maps
- build an interactive globe or map in the browser

## When to choose
- you need ready-made world/country geometry for D3 or Observable maps
- you want small, quantized TopoJSON instead of raw shapefiles
- you need multiple resolutions (110m/50m/10m) of the same boundaries

## When to avoid
- you need up-to-date political boundaries or recent Natural Earth versions
- you need projected (not spherical) coordinates or custom projections baked in
- you need sub-national administrative units

## Facets
- artifact type: dataset
- maturity: stable
- function: data-visualization, geospatial
- domain: data-visualization
- platform: browser, cross-platform
- tags: topo, natural-earth, d3, world-map, geographic-data, static-dataset, maps, geospatial, web-server, nodejs
