The document discusses the Publicspending.gr (PSGR) program in Greece, which aims to provide transparency in public expenditure through network analysis and visualization of spending data. The key points are: 1) PSGR manifests the value of open data and ex-ante reporting of government decisions, shifting the paradigm for 40,000 public servants. 2) Since launching in 2011, PSGR has progressed from believing open data is valuable to realizing it requires refining like chiseling jewelry from rocks in a goldmine. 3) Network analysis is a basic tool used by PSGR to analyze and visualize linked spending data, enabling the study of relationships between important payees and payers and economic impacts
