#### Passing in geospatial data
You can pass geospatial data into the Map embeddable by configuring the layerList parameter with a layer with `GEOJSON_FILE` source.
Geojson sources will not update unless you modify `__featureCollection` property by calling the `setLayerList` method.
```
const factory = new MapEmbeddableFactory();
const state = {
layerList: [
{
'id': 'gaxya',
'label': 'My geospatial data',
'minZoom': 0,
'maxZoom': 24,
'alpha': 1,
'sourceDescriptor': {
'id': 'b7486',
'type': 'GEOJSON_FILE',
'__featureCollection': {
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Polygon",
"coordinates": [
[
[0, 0], [10, 10], [10, 0], [0, 0]
]
]
},
"properties": {
"name": "null island",
"another_prop": "something else interesting"
}
}
]
}
},
'visible': true,
'style': {
'type': 'VECTOR',
'properties': {}
},
'type': 'VECTOR'
}
],
title: 'my map',
}
const input = {
hideFilterActions: true,
isLayerTOCOpen: false,
openTOCDetails: ['tfi3f', 'edh66'],
mapCenter: { lat: 0.0, lon: 0.0, zoom: 7 }
}
const mapEmbeddable = await factory.createFromState(state, input, parent);
mapEmbeddable.setLayerList([
{

'label': 'My geospatial data',
'minZoom': 0,
