Data Scientist at Samsung SDSGo through what I have done
Through analysis of European paintings available online, I have been quantitatively studying evolution of painting styles and color palette as well as relationships between individual artists' style and their career changes.
Through analysis of patent records provided by the United States Patent and Trademark Office, European Patent Office, and World Intellectual Property Organization, I have been investigating how technologies change over time.

It is based on the recent administrative district map (city level - Feb. 2016).
This interactive Sankey diagram quantitatively shows the change of the U.S. patents' primary technology classification code over time.
In this visualization, you can interactively change the parameters of Vicsek's model.
This movie represents the evolution of events in the Annals of the Joseon Dynasty spanning 473 years.
It is like Google N-gram but not exactly same. This visualization is based on the large-scale Korean historical database such as the Annals of the Joseon Dynasty spanning 472 years (1392-1863), the Daily Records of the Royal Secretariat spanning 272 years (1623-1894), and the Border Defense Council of Joseon spanning 276 year (1617-1892).
This country-level patent citation network was built with all of the Google patent HTML files up to December 2014.
This technology category network was buit with cumulative co-occurrence values between technology categories in the United States patent records.
This movie shows the evolution of each node's strength in the co-occurrence network constructed by the U.S. patent records spanning 225 years, where a node indicates a 9-digit U.S. technology classification code in the U.S. patent records, the strength of a node is defined by the sum of neighboring link weights of the node, the radius and the opacity of a circle in this movie indicates the strength of a technology code, and the color of a circle represents its category.
