map: Is map an arbitrary spatial graph?

Showing a conference location is a geographic-map use. A draggable concept graph expresses knowledge relationships; it is not automatically the map primitive. The registry’s Leaflet reference is a Web implementation detail.

Start with these properties

center gives the initial center as latitude followed by longitude. zoom sets the initial zoom level, and markers lists locations. Within each marker, lat and lng mean latitude and longitude, while label supplies its description.

{
  "id": "office-map",
  "type": "map",
  "props": {
    "center": [
      37.7749,
      -122.4194
    ],
    "zoom": 12,
    "tileStyle": "carto-dark",
    "markers": [
      {
        "lat": 37.7749,
        "lng": -122.4194,
        "label": "HQ",
        "intent": "info"
      },
      {
        "lat": 37.785,
        "lng": -122.409,
        "label": "Office 2",
        "intent": "success"
      }
    ],
    "fitMarkers": true
  }
}

tileStyle chooses a basemap style and fitMarkers: true requests a view that includes every marker. A marker’s intent supplies presentation semantics, such as information or success coloring; it does not verify the place. This is a flat-map configuration; a globe requires a separately supported rendering choice.
