DDG-Explorer

DDG Explorer is a tool that allows the user to view and query Data Derivation Graphs (DDGs). It has the following functionality:

  • Visualization of DDGs, with the ability to expand and contract portions of the graph to selectively show or hide details.
  • Ability to view the data or R functions referenced by pieces of the DDG
  • Ability to query a DDG to discover how an input data value gets used, or what data and processing steps lead to the derivation of a particular output value
  • Ability to compare R scripts used to generate different DDGs
  • Ability to search for where a particular data file is used or generated.
