Data Source: Wikidata + Wikimedia Commons. 1M+ people + 700k orgs, entities are limited to Europe and North America, but notable entities from other countries appear. Feed section lets you scroll through dynasties, even from 1500, I find it to be a very interesting Discover feature. Built using ArangoDB, Redis, Vue + Cytoscape.js, data processing from Wikidata full dump took approx. 1-2 days, and due to space occupied I set a notability count on entities.
