• This paper was hugely inspirational to me personally, as it clearly illuminates the concept of multidimensional aggregation in the form of "data cubes". Many data visualizations deal with aggregated multidimensional data, and the data cube concept sheds light on the full structure of possible ways to aggregate.
  • Note: "data cubes" relates to the concept of "binned aggregation" discussed in the imMens paper.
