Paper: Conceptualizing Visual Uncertainty in Parallel Coordinates
Visualization is largely defined as the transformation of data into images. Visualization tools don’t have a way of assessing their output, though: were there enough pixels to represent all the data?...
View ArticlePaper: Storytelling, The Next Step for Visualization
Visualization is often considered to consist of three phases: exploration, analysis, and presentation. While the former two topics are covered well in the literature, there has been very little work...
