Verity Visualization: Visual

abstract Visualized data often has dubious origins. One way to deene data lineage is by describing the uncertainty. In addition, diierent forms of uncertainty and errors are also introduced as the data is derived, transformed, interpolated, and nally rendered. In the absence of integrated presentation of data and its associated uncertainty, the analysis of the visualization is incomplete at best and often leads to inaccurate or incorrect conclusions. This paper presents several techniques of presenting data together with uncertainty. The idea behind these techniques can be applied to both spatial (e.g. surface) and temporal (i.e. animation) domains. We describe these techniques of representing the truths about the data as verity visualization. The same techniques can also be used to make the users aware of the data quality or to emphasize and draw their attention to the uncertainty.
