# XWUIGISMap

Zero-dependency slippy map. Renders OSM-scheme raster tiles as DOM images with fractional, cursor-anchored zoom, draws polygons, polylines, rectangles and true-metre circles on a canvas overlay, clusters markers in screen space, and hosts a keyboard-operable drawing surface. Loads no third-party map library: window.L, maplibregl and mapboxgl all stay undefined. Acts as the IXWUIGISMapHost that xwui-gis-legend, xwui-gis-layer-panel, xwui-gis-basemap-picker, xwui-gis-search-box and xwui-gis-draw-toolbar attach to.

## Basic Usage

A keyless OpenStreetMap basemap with two pins. No API key, no map library, no window.L.
