## 🚀 Quick Start

```vue
<template>
  <Maplibre :options="mapOptions" style="height: 500px" @load="onMapLoad">
    <!-- GeoJSON Data Source -->
    <GeoJsonSource :data="geoJsonData">
      <FillLayer :style="fillStyle" />
      <CircleLayer :style="circleStyle" />
    </GeoJsonSource>

    <!-- Interactive Marker -->
    <Marker :lnglat="[0, 0]" :draggable="true">
      <div class="marker">📍</div>
    </Marker>

    <!-- Popup -->
    <PopUp :lnglat="[0, 0]" :show="true">
      <div class="popup-content">
        <h3>Welcome to Vue3 MapLibre GL!</h3>
        <p>Interactive maps made easy with Vue 3</p>
      </div>
    </PopUp>

    <!-- Geolocation Control -->
    <GeolocateControls position="top-right" />
  </Maplibre>
</template>

<script setup>
import { ref } from 'vue';
import {
  Maplibre,
  GeoJsonSource,
  FillLayer,
  CircleLayer,
  Marker,
  PopUp,
  GeolocateControls,
} from 'vue3-maplibre-gl';
import 'vue3-maplibre-gl/dist/style.css';

const mapOptions = ref({
  style: 'https://demotiles.maplibre.org/style.json',
  center: [0, 0],
  zoom: 2,
});

const geoJsonData = ref({
  type: 'FeatureCollection',
  features: [
    {
      type: 'Feature',
      geometry: { type: 'Point', coordinates: [0, 0] },
      properties: { name: 'Sample Point' },
    },
  ],
});

const fillStyle = ref({
  'fill-color': '#088',
  'fill-opacity': 0.8,
});

const circleStyle = ref({
  'circle-radius': 6,
  'circle-color': '#007cbf',
});

function onMapLoad(map) {
  console.log('Map loaded:', map);
}
</script>

<style>
.marker {
  font-size: 24px;
  cursor: pointer;
}

.popup-content {
  padding: 10px;
  max-width: 200px;
}
</style>
```

```

## 🌟 Advanced Example with Composables

```vue
<script setup>
import { ref } from 'vue';
import {
  useCreateMaplibre,
  useFlyTo,
  useMapEventListener,
  useCreateGeoJsonSource,
} from 'vue3-maplibre-gl';

const mapContainer = ref();
const mapStyle = ref('https://demotiles.maplibre.org/style.json');

// Create map with enhanced error handling
const { mapInstance, setCenter, setZoom } = useCreateMaplibre(
  mapContainer,
  mapStyle,
  {
    onLoad: (map) => console.log('Map loaded:', map),
    onError: (error) => console.error('Map error:', error),
    debug: true,
  },
);

// Add smooth animations
const { flyTo } = useFlyTo({ map: mapInstance });

// Create reactive data source
const { setData } = useCreateGeoJsonSource({
  map: mapInstance,
  id: 'my-source',
  data: { type: 'FeatureCollection', features: [] },
});

// Listen to map events
useMapEventListener({
  map: mapInstance,
  event: 'click',
  handler: (event) => {
    flyTo({
      center: event.lngLat,
      zoom: 12,
      duration: 2000,
    });
  },
});
</script>
