The paint and layout properties for the layers depend on the type of the layer. They are passed as a dict corresponding to the Layer Style Spec.
 
For example, to set the radius and the color for a circle layer, the paint property looks like this:
 
paint = {\n    \"circle-radius\": 5,\n    \"circle-color\": \"yellow\"\n}\n
 
The value for any layout property, paint property, or filter may also be specified as an expression. For details see Expressions.
 
For example, if the source of your layer has a color property that contains the color of the feature, you can use the following expression:
 
paint = {\n    \"circle-radius\": 5,\n    \"circle-color\": [\"get\", \"color\"]\n}\n
 
A more complex expression where the color depends on the type property of the layer's source might look like this:
 
paint={\n        \"circle-color\": [\n            \"match\",\n            [\"get\", \"type\"],\n            # darkred if type == \"mid\"\n            \"mid\",\n            \"darkred\",\n            # darkgreen if type == \"major\"\n            \"major\",\n            \"darkgreen\",\n            # else blue\n            \"darkblue\",\n        ]\n}\n
 
Filter features of a source according to its magnitude property:
 
# Only show features where magnitude >= 5\nfilter = [\">=\", [\"get\", \"magnitude\"], 5]\n

MapLibre for Python provides the following reactive inputs:
 
     
  • map-on-click event: Sends the coordinates of the location that was clicked on. The name of the input event corresponds to the output id.     For output_maplibregl(\"maplibre\") you need to listen to input.maplibre.
    •  
  • feature-on-click event: Sends the properties of the feature that was clicked on. The name of the \u00ecnput is made up of the output id + layer + layer id.      For output_maplibregl(\"maplibre\") and a layer with id=test you need to listen to input.maplibre_layer_test.

The paint and layout properties for the layers depend on the type of the layer. They are passed as a dict corresponding to the Layer Style Spec.
 
For example, to set the radius and the color for a circle layer, the paint property looks like this:
 
paint = {\n    \"circle-radius\": 5,\n    \"circle-color\": \"yellow\"\n}\n
 
The value for any layout property, paint property, or filter may also be specified as an expression. For details see Expressions.
 
For example, if the source of your layer has a color property that contains the color of the feature, you can use the following expression:
 
paint = {\n    \"circle-radius\": 5,\n    \"circle-color\": [\"get\", \"color\"]\n}\n
 
A more complex expression where the color depends on the type property of the layer's source might look like this:
 
paint={\n        \"circle-color\": [\n            \"match\",\n            [\"get\", \"type\"],\n            # darkred if type == \"mid\"\n            \"mid\",\n            \"darkred\",\n            # darkgreen if type == \"major\"\n            \"major\",\n            \"darkgreen\",\n            # else blue\n            \"darkblue\",\n        ]\n}\n
 
Filter features of a source according to its magnitude property:
