我正在尝试按县编码加州的互动地图。当用户在县内徘徊或点击（我还没有确定）时，会出现工具提示或弹出窗口，其中包含该县特定的数据。
我正在使用我在维基百科上找到的内联SVG文件：Map of California by County
每个“折线”代表一个县并且有一个id（例如id =“_ x30_01_Alameda”）。有没有办法对xml进行编码，以指定在悬停时点击或在点击该ID时触发的事件？
显然，我还没有和SVG合作过多。是否有更好的方法来按县创建交互式地图？
以下是我要修改的代码示例。我已经在“县动画”的'折线'元素中添加了类，现在我只想弄清楚如何在悬停时为每个县添加一个包含特定信息的弹出窗口：
更新
所以我在折线内添加了标题“Hello World”，所以现在当用户将鼠标悬停在特定的县上时，工具提示会出现。有关如何使用工具提示的任何建议直接显示在每个县吗？只能用CSS和绝对定位来完成吗？如果是这样，那听起来像是一场噩梦。
感谢您的帮助！
