6. Stories are how numbers talk to people.
-Thomas Davenport
By visualizing information, we turn it into a
landscape that you can explore with your
eyes, a sort of information map. And when
you’re lost in information, an information
map is kind of useful.
―David McCandless
Numbers have an important story
to tell. They rely on you to give
them a clear and convincing voice.
―Stephen Few

Editor's Notes
Government Accountability Office report: Program Evaluation: Improving the Flow of Information to Congress
Presenting data visually supports viewer cognition
Graphic elements can reduce overload on working memory by doing some of the thinking for the reader. By visually organizing and emphasizing information, graphic design makes it more accessible for the reader, increasing the capacity to engage with the words and data.
Effective data presentation, where we use graphic visualization to emphasize information, speeds the acquisition of that information and reduces the opportunity for misinterpretation.
Chart example without data labels
Chart example without data labels
or use data that is visual by nature (charts, maps, etc.)
use imagery to illustrate the data, (use imagery in place of traditional charts)
Does your data tell a visual story (use imagery to enhance communicating data that is not visual in nature)
