Extension:Graph/Demo/Sparql

Number of museums per country
This graph pulls data from three wikidata queries
 * 1) Number of museums by country
 * 2) Country names - note that labels are localized using a list "ru,en", meaning first it will try to find a label in Russian, followed by English if Russian is not available.
 * 3) Country populations

This graph draws a map based on topojson map data, keyed by Wikidata ID. For each region, it looks up the number of museums, population, and region name from the 3 above queries. The color is determined by logarithmicly scaling museums/population. On mouseover, the country's name and museum count is shown.

Largest cities
