Abstract

CityPlot generates an extended version of a traditional entity-relationship diagram for a database. It is intended to provide a combined view of database structure and contents. The graphical output resembles the metaphor of a city. Data points are visualized according to data type and completeness. An open source reference implementation is available from http://cran.r-project.org/.
