在上面的基础上，怎样使用插件MovingMarker实现标记移动效果。
效果
在这里插入图片描述
实现
1、插件地址
https://github.com/ewoken/Leaflet.MovingMarker
2、下载仓库代码，复制其MovingMarker.js核心文件
3、引入leaflet所需的文件以及该js文件
<link rel="stylesheet" href="https://unpkg.com/leaflet@1.7.1/dist/leaflet.css" />
<script type="text/javascript" src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
<script type="text/javascript" src="./js/MovingMarker.js"></script>
4、完整示例代码
