VISUALIZING DOCUMENT REVISION HISTORY USING LAYERS

摘要

Systems, servers, methods, media, and programs for generating a graphical comparison of data files are provided. A relationship is computed between a first data file and a second data file. The relationship represents at least one change from the first data file to the second data file. A transformation is computed in accordance with predefined transformation operations based on the relationship between the first data file and the second data file. The transformation includes at least one of the predefined transformation operations and is executable for representing the change from the first data file to the second data file. A graphical comparison of the data files is generated. The graphical comparison is configured to visualize the change from the first data file to the second data file by executing the transformation.
