This visualization displays a segment of the Moose River in New York, rendered as two wide-river shoreline reaches from a GeoJSON file. The map shows the river’s course using blue line strings, with each feature annotated with attributes such as reach type, size class, and port code. The example uses the geojson.io interface to present the geographic data, highlighting river reaches within the Black River HUC8 watershed and Northeast Lake Ontario ecoregion, with each line colored by its attribute values.
