Leaflet.js -如何绘制自动覆盖一组标记的多边形？

var map = L.map('map').setView([51.505, -0.09], 13);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors',
    maxZoom: 18,
}).addTo(map);

var markers = [
    [51.5, -0.09],
    [51.51, -0.1],
    [51.52, -0.12],
    // 添加更多标记...
];

var polygon = L.polygon(markers).addTo(map);

polygon.setStyle({
    fillColor: 'red',
    color: 'blue',
    weight: 2,
});
