One more thing… I notice that I used the icon name “airplane-15”. This icon
does not actually exist in the default sprite sheet that arches includes, so
you will need to make sure you specify icons that are available to the map to
display or else you won’t see anything on the map. Hopefully that’s obvious,
but if you try to use the style below verbatim it will not work by default.
You could change “airplane-15” to something like “music-15” which is included
in the default sprite sheet (supported icons for the default sprite sheet can
be found here:
