Views 		FAQ

This page helps you to understand the various possibilities to display results on Wikidata Query. The query example page contains many good examples you can try!

After running a query, you can choose with the "Display" button which result view you want to display. Depending on your query and the data type, some of the views will be available. 

#Countries in European Union with Flags and Population
# to be displayed as
# 1) Table
# 2) Image Grid
# 3) Map
# 4) Bar Chart
# 5) Bubble Chart
SELECT ?country ?countryLabel (MAX(?population) AS ?Population) (SAMPLE(?flag_image) AS ?Flag) (MAX(?coordinate) AS ?coor)

Display button. Try the query to the left as Table, Image Grid, Map, Bar Chart and Bubble Chart

Default View edit

The default view can be changed for each SPARQL query by using a comment 

#defaultView:[NAME]

For example: 

#defaultView:ImageGrid

Table (default) edit

Shows the result data as table. It is the default view for results and can display every data type.

This will map every variable from the SPARQL select clause to a formatted table column.

  •  
    Table Result
  •  
    Table Result on small screens with flipped columns

Image Grid edit

The #defaultView:ImageGrid shows the result data as a grid with images.

Every grid item has a big picture and opens the gallery when clicking on it.

Contents an item is the formatted row data.

Variable Data Type Mapping Description
* Commons Media Grid Item Image columns will create a grid item.

Rows containing no image will be ignored.

Options:

Option name Type Description
hide One or more variable names (strings, starting with ?), single value or array Don’t show these variables in the result. 
#Even more cats, with pictures
#added before 2016-10
#defaultView:ImageGrid
SELECT ?itemDescription ?itemLabel ?item ?pic
WHERE
{
	?item wdt:P31 wd:Q146 . 
	OPTIONAL {
		?item wdt:P18 ?pic
	} 
	SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}

Map edit

The #defaultView:Map shows the result data as map with OpenStreetMap data.

Variable Data Type Mapping Description
* Coordinate Map Marker Columns will create a marker on the map.
Content of that marker is the formatted row data.
?layer Map Marker Layer Creates a colored map layer that allows filtering.
?rgb Color Color Map Marker Example 000000 for black color.

Options:

specified using #defaultView:Map{"hide":["?foo", "?bar"],"layer":"?bar"} using the array if there are multiple variables.

Option name Type Description
hide One or more variable names (strings, starting with ?), single value or array Don’t show these variables in the result.
layer One or more variable names (strings, starting with ?), single value or array Use these variables for the map layer, instead of the default ?layerLabel, ?layer.
markercluster boolean or object
  • If the value is an object, pass these options to Leaflet.markercluster, a map plugin for clustering nearby map markers. (If the value is the empty object {}, Leaflet.markercluster is enabled with its default options.) For example #defaultView:Map{"markercluster": {"maxClusterRadius": 1}}
  • If the value is true (default for queries without map layers), Leaflet.markercluster is enabled with a special set of options that doesn’t cluster any nearby map markers (it only “spiderfies” markers with exactly identical coordinates) and attempts to replicate the default map look as much as possible. The code is #defaultView:Map{"markercluster": "true"}
  • If the value is false (default for queries with map layers), Leaflet.markercluster is not enabled.


#Big cities, grouped into map layers by population
#defaultView:Map

Technically, any well-known text literal can be displayed, not just a point coordinate.

Some Geoshapes are available via property geoshape (P3896). See this example for the countries. 

#Geoshapes of counties
#defaultView:Map
SELECT DISTINCT ?country ?countryLabel ?geoshape (?countryLabel AS ?layer )
WHERE
{
  ?country wdt:P31 wd:Q3624078.
  ?country wdt:P3896 ?geoshape.

Geometry values can also be constructed in SPARQL using functions like CONCAT() and STRDT() – see this map of Czech railway lines for an example of LINESTRING() geometry. 

#defaultView:Map

Mobile / Responsive edit

Result views are made to work on different devices and resolutions. Their appearance may change depending on the space they can use.

Embed Mode edit

Result views can be linked or embedded via iframes. You can get the regarding link or code by clicking Link in the above menu. See the difference: link to a query and link to a result

or the embed code:

<iframe style="width:80vw; height:50vh;" scrolling="yes" frameborder="0" src="http://tinyurl.com/zwf4k2w">

Download results edit

 
Download results buttons

There are several ways to export the results of a query.

JSON, TSV and CSV are three different open-standard formats to download the data.

You can also download some of the graphic views as a SVG file: this feature works with all the views except table, image grid, timeline, graph builder, map, and graph.

Default View edit

The default view can be changed for each SPARQL query by using a comment: 

#defaultView:[NAME]

For example: 

#defaultView:ImageGrid

Result view options edit

Result views can be configured with various options, which are specified in JSON (Q2063) format, either following the defaultView comment or following a separate view comment. 

#defaultView:Map{"layer": "?typeLabel"}
#view:ImageGrid{"hide": "?coords"}

External tools edit
