使用 L.polygon繪畫連接四間酒店的多邊形，四間酒店的名稱及坐標如下：
香港尖沙咀凱悅酒店 : 22.297696623540645, 114.17403305500363
九龍香格里拉 : 22.297349192568806, 114.17705858671009
九龍酒店 : 22.29592967990824, 114.17179072831338
半島酒店 : 22.295344002650047, 114.17183364365674
例子如下:
var polygon = L.polygon([[22.297696623540645, 114.17403305500363],[22.297349192568806, 114.17705858671009],[22.29592967990824, 114.17179072831338], [22.295344002650047, 114.17183364365674]], {color: 'red',weight:8,fillColor:'blue',fillOpacity:1}).addTo(map);
