# MapboxGlowCircle

> 炫光圆效果，实心内核加模糊光晕，可选呼吸脉冲。

## 简介

`MapboxGlowCircle` 在点要素上渲染炫光圆：实心内核 + 模糊光晕，`pulse` 开启呼吸脉冲；`color` / `radius` / `glowScale` / `duration` 控制外观与节奏。

## 用法

切换主色查看带呼吸脉冲的炫光：

```vue [GlowExample.vue]
<script setup lang="ts">
import type { FeatureCollection } from 'geojson'

withDefaults(defineProps<{ color?: string }>(), {
  color: '#f59e0b'
})

const data: FeatureCollection = {
  type: 'FeatureCollection',
  features: [
    { type: 'Feature', properties: {}, geometry: { type: 'Point', coordinates: [116.397, 39.908] } },
    { type: 'Feature', properties: {}, geometry: { type: 'Point', coordinates: [116.46, 39.92] } }
  ]
}
</script>

<template>
  <div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
    <MapboxMap :options="{ style: 'mapbox://styles/mapbox/dark-v11', center: [116.43, 39.913], zoom: 11 }">
      <MapboxGlowCircle :data="data" :color="color" pulse />
    </MapboxMap>
  </div>
</template>
```
