Markup Result
Simple map with a single marker, custom size, and no minimap
{{Map with marks | width=400 | height=150 | lat=37.8 | lon=-122.4 | zoom=5 | minimap=false |

  { "lat": 37.8, "lon": -122.4 }

}}
Two markers with labels - one as diamond shape, one uses an image from Commons
Text label can be customized with all of Vega text mark parameters by prepending "text" to their name

Data from Commons Dataset
Same as above, but this time the data is stored on Commons in a table Data:Sandbox/Yurik/Street map with marks sample.tab

Show all Armenian heritage sites, by querying it from Wikidata
The query result should have the same columns (fields) as in the other examples (text, img, ...), except coordinates should be returned as coord column 
{{Map with marks | lat=40.347 | lon=47.260 | zoom=6 | colorScaleField=type | wdqs=
# Each location should show only once. This query may output all the same values as in the other examples, such as "text", "img", and others.
SELECT (SAMPLE(?coord) as ?coord) (SAMPLE(?type) as ?type)
WHERE {
  ?item wdt:P3170 ?heritageId .
  ?item wdt:P625 ?coord .
  ?item wdt:P31 ?type .
}
GROUP BY ?item
}}
