Archaeological data used for the paper Exploring Economic Integration of Peasant Settlements in Roman Central Spain (1st - 3rd c. AD). The supplement is composed by three CSV files recording respectively the presence and frequency of an artefact chrono-type at a site, the adjacency matrix (MATRIX_SITE-CHRONOTYPE_CARPETANIA.csv), the attribute information per site (ATTRIB_SITES_CARPETANIA.csv) and the attribute information per artefact chrono-type (ATTRIB_CHRONOTYPES_CARPETANIA.csv). Also included are the raw .graphmlz files relating to the analyses carried out which include, among other data, the Louvain modularity. In order to view and analyse the .graphmlz files provided in this archive, you can use the Visone software, a tool for visualizing and analyzing networks: To view these .graphmlz files, first download and install Visone software from their official website (https://visone.ethz.ch/). Then, download the .graphmlz files from the Zenodo archive. Open Visone, and navigate to 'File' > 'Open' to access the downloaded files.
