Wikidata Historymaps

The project fetches history data from wikidata (with time/location) and displays them using google maps. Data fetching starts with a person (i.e. its wididata id) and recursivly loads a number of data of ancestor and descendants. Places of historic events are clickable markers, where a description window can be shown. There are lines drawn between places of a persons history and between places of ancestors to descendants.

Some interesting aspects from a programming perspective: the wikidata barcode logo is 'wiki' in morse code (ref). Wikimedia commons image urls are of the form a/ab/(filename), where 'ab' are the first characters of the md5 hash of the filename.
