This paper investigates the analytical visualizations of archived images produced by the Russian art historian and computer scientist Lev Manovich and his team, the 'Cultural Analytics Lab' . The observer's point of view in these visualizations will be studied in the methodological framework of post-Greimasian semiotics. Whilst these visualizations have scientific purposes, some of them are considered as aesthetically relevant objects, and their transformation from scientific tools into aesthetic objects will be analyzed through Peircean Theory of diagrams.
