Hi,  
Could someone post an example how to use kml, gpx or topojson to create for example polyline/ track as a layer?

Best Regards,  
Toni

The [documentation describes](https://flows.nodered.org/node/node-red-contrib-web-worldmap) how to use it.

Yes, I know. I need some example, because I cannot get kml to work.

So provide the flow you are using with KLM so people can help you figure out what is the issue.

Unfortunately your flow isn't currently importable.Please read the following post [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506) and then edit the above message.

But here's an example of a working gpx

````auto
