Understanding GeoJSON maps
What GeoJSON contains
GeoJSON is a JSON-based format for geographic features. A FeatureCollection contains Features, and each Feature combines geometry with a properties object containing names, categories or other attributes.
Coordinates normally use WGS84 longitude first, then latitude. Geometry can be a Point, LineString, Polygon, a multipart equivalent or a GeometryCollection.
How to read the viewer
The map shows geometry placement while the source text preserves feature properties. Point clusters summarize nearby rendered points at the current zoom; they do not merge or alter source features.
A plausible map position does not prove the file is correct. Check coordinate order, geometry type, bounds and important properties before using the data downstream.
