It's well known that visualizations can lie, that is, distort the true
relationship between the variables and records being represented
visually. The precursor of this topic was Darrell Huff's 1954 book on
How to Lie with Statistics. Others have provided indirect measures
involved in the synthesis of the visualization. For example Edward
Tufte with chart noise and ink metrics in his book the Visual Display
of Quantitative Information. In this presentation I will describe
different approaches to measuring truth in visualizations. I will
define what I mean by truth. I will then describe an open source
analysis and visualization environment called Weave that we have
developed and its architecture for generating descriptions of
visualizations developed for ADA compliance. Finally I will give
examples of measuring truth (work in progress).
