Add text to nodes
The following query prints all nodes in Croatia that have a place=city tag and annotates them with the value found in the population tag:
area[ 'ISO3166-1' = 'HR' ];
node[place=city](area);
out;
{{style:
node {
text: population;
}
}}
It's also possible to use eval(‥) to generate somewhat more dynamic text:
node, way, relation {
text: eval("tag('name') . ' (' . tag('wikidata') . ')'");
}
any allows to state a preferred value:
node, way, relation {
text: eval("any(tag('short_name'),tag('name'))");
}

TODO: Can the VBZ-relations colour attribute value be used to dynamically set a line's color using the eval and tag functions?
Color restaurants in Switzerland according to their names
The purpose of the following demonstration is to show how nodes can be colored using their fill-color, color and fill-opacity attribute:
{{geocodeArea: Switzerland }};
node
[ amenity = restaurant ]
[ name ~'^(Rössli|Bahnhof|Löwen|Kreuz|Sternen|Hirschen|Post|Krone|Bären|Sonne|Linde|Traube|Ochsen)$' ]
( area );
out;
{{style:
node { fill-opacity: 1 }
node [name=Rössli] { fill-color: grey ; color: grey }
node [name=Bahnhof] { fill-color: black ; color: black }
node [name=Löwen] { fill-color: red ; color: red }
node [name=Kreuz] { fill-color: olive ; color: olive }
node [name=Sternen] { fill-color: orange ; color: orange }
node [name=Hirschen]{ fill-color: maroon ; color: maroon }
node [name=Post] { fill-color: purple ; color: purple }
node [name=Krone] { fill-color: beige ; color: beige }
node [name=Bären] { fill-color: brown ; color: brown }
node [name=Sonne] { fill-color: yellow ; color: yellow }
node [name=Linde] { fill-color: lime ; color: lime }
node [name=Traube] { fill-color: navy ; color: navy }
node [name=Ochse] { fill-color: teal ; color: teal }
}
