The document outlines the various stages of data management from collection to analysis and how visualization can aid at each stage. It discusses using visualizations like trees, graphs and networks to plan the data management process and understand relationships between datasets during collection. During collection, visualization can also help understand results from data mining algorithms and the structure of files. At the assurance stage, graphical summaries produced from statistical operations on datasets can be used for security and quality checks. Visualizations like multi-dimensional maps and volumes can then be used for process monitoring and quality assurance. Visualization is also discussed as a way to understand and analyze large web archives by examining file hierarchies and types during preservation. Finally, different visualizations can be applied during analysis depending on user needs
