  "summary": "Lightweight open-source JavaScript library for interactive tile-based web maps with markers, vector layers and a large plugin ecosystem",
  "description": "Leaflet is an open-source JavaScript library for building interactive maps in the browser, created by Volodymyr Agafonkin and maintained by a community of contributors. It renders raster tile layers from any XYZ or WMS source, draws markers, popups, polylines, polygons and GeoJSON overlays, and handles touch and keyboard interaction with a small footprint and no dependencies. Hundreds of plugins add clustering, heatmaps, drawing, routing and vector-tile support, and wrappers exist for React, Vue and Python (Folium, ipyleaflet). It is the common choice for dashboards and research pages that need an OSM base map with a few overlays. Leaflet does not include map data or tile hosting, renders raster tiles rather than styled vector tiles by default, and depends on plugins for 3D, rotation and heavy vector workloads.",
  "capabilities": [
    "Raster tile layers from XYZ and WMS sources",
    "Markers, popups, vector shapes and GeoJSON layers",
    "Mobile-friendly touch and keyboard interaction",
    "Plugin ecosystem for clustering, drawing, heatmaps and vector tiles",
    "Framework wrappers for React, Vue and Python"
  ],
  "workflows": [
    "Embed an OSM base map with clustered property markers in a web page",
    "Render GeoPandas output as an interactive map through Folium"
  ],
  "advantages": [
    "Small, dependency-free and BSD-licensed",
    "Works with any tile provider",
    "Large plugin and tutorial base"
  ],
  "limitations": [
    "Raster-first; vector tiles and rotation need plugins",
    "No bundled data or tile hosting",
    "Less suited to heavy client-side vector rendering"

    "A tile source such as OSM-derived tiles or a commercial provider"

  "comparison_notes": "MapLibre GL renders vector tiles with WebGL and supports rotation and 3D, at the cost of a heavier runtime; Leaflet is simpler for raster tiles and overlays. Mapbox and Google Maps Platform are hosted services with their own SDKs and metered pricing.",
