The document summarizes a presentation given at the NASW annual meeting on November 6, 2010 by David Harris. The presentation discussed how data visualization can help understand data by finding stories and errors within it. It notes that while researchers are often poor at visualization because they include too many details, journalists are generally better at it because they can take the audience's perspective. The presentation provided tips on when and how to effectively visualize data, and used an example of visualizing individual criminal histories.
