Visualizing SPARQL query results on the census


After successfully converting to RDF a subset of the whole sample of the Dutch historical censuses, some SPARQL queries have been launched against the dataset. The goal of these queries is to retrieve the population of men living in the province of Noord-Brabant, per municipality, during the census years 1879 and 1889, sorted in descendant order. The following figures use the Google Visualization API to draw the results in two different Geo Charts, outputting data of 1879 and 1889, respectivelly.
