[I have tried searching using google and the search option - I promise]

I wish to embed an Open Streetmap Map into my website (which is easy using LeafletJS), and then I want to display the boundary for a "relation" you have stored. Looking at the xml I can see the relation is made up of multiple 'ways' and for each 'way' I could seek to download a 'node'. From here I could traverse the xml and locate each GPS co-ord and then add it programatically to the map using Leaflet but this seems (to me) overcomplicated. Is this what is generally done or is there a blindingly obvious programatic way that I have not seen? I can imagine this question should be directed here or to the Leaflet folks -so apologies if this is a wrong posting

Unrelated to getting the Relation into Leaflet, if you're planning on using tiles from the "default" style then there's an associated usage policy linked to from the copyright page.

If you only want to use a single relation statically, and don't need updates then you can download the data in GeoJSON format from Overpass Turbo. I think Leaflet then allows you to use GeoJSON layers if you store it on your site somewhere.

Thank you! I must admit that when I went to Overpass I scratched my head as to how to find the "relation" from OSM - but a quick question with ChatGPT led to the following Overpass query

[out:json]; relation(9456324); (._;>;); out;

which then allowed me to download the GPS points as you describe. Perfect!
