Analysis http://live.payola.cz/analysis/f7953042-6d29-4cb6-9eef-016f56824b32 returns for each business entity (bidder) three triples: type (gr:BusinessEntity), year (of entity registration) and count (of public contracts). However, a link/node graph (circle, tree etc.) only links a single business entity resource to gr:BusinessEntity. Other business entities are wrongly linked, by rdf:type links, to entities corresponding to years. See example in screenshot: the business entity in upper-left is linked by the ex:year property to year 1992, and, wrongly, by the rdf:type property to year 2003.
