## What it is
A JavaScript library for visualizing 3D building geometry on web maps using OpenStreetMap data. It renders extruded building shapes over map tiles and supports GeoJSON tile loading.

## Use cases
- display 3d buildings on a web map
- visualize openstreetmap building geometry in the browser
- add extruded building footprints to a leaflet map
- render city buildings in 3d from osm data
- embed an interactive 3d map viewer in a website

## When to choose
- you need lightweight browser-based 3D building visualization from OpenStreetMap data
- you want a simple script-tag integration with map tiles and GeoJSON building tiles
- you need a Leaflet-compatible 3D buildings layer

## When to avoid
- you need actively maintained software with recent releases and support
- you need full 3D globe or terrain rendering rather than building extrusions
- you require a license with clear terms, since the project's license is non-standard

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, graphics, geospatial
- domain: web-development, frontend, data-visualization
- platform: browser
- tags: openstreetmap, 3d-buildings, webgl, maps, geojson, javascript, web-server
