Ghost card to display a GPS track with Leaflet

I’m looking for a way to display a GPS track in an article with Leaflet with the Dawn theme. Has anyone ever made such a card? How would I do that?

Looks like you can put the code into an html card (don’t forget to load the leafletjs code and add the Div you want to put the map in). Or you could put everything except the target Div into code injection.

Cool idea. Can I upload the GPX file in Ghost somehow so that I can access it from the Leaflet JS code?

Answering myself: Yes, I can. Just upload it as file attachment. Done.

Great. Sorry for not replying sooner! :)
