submission. Visualizing these work histories can yield valuable insights into patterns of
student work, common error patterns, and so on. Currently each system must provide its own
data visualization system, or must rely on external tools, such as R or Excel. However, the
actual values stored in snapshot-based data sets are similar between systems, and, given
agreement upon conventions, could be visualized with a common system. We have built a …

Many systems collect snapshots of student work, typically after each compile, save, or submission. Visualizing these work histories can yield valuable insights into patterns of student work, common error patterns, and so on. Currently each system must provide its own data visualization system, or must rely on external tools, such as R or Excel. However, the actual values stored in snapshot-based data sets are similar between systems, and, given agreement upon conventions, could be visualized with a common system. We have built a prototype web service called Snapviz. Snapviz displays snapshot data from tab-delimited data files uploaded by users.
