### Data Visualization for Drought & Cross Border Crisis

1. 1. Data Visualization for Drought & Cross Border Crisis October 31, 2013 Angela Zoss Data Visualization Coordinator Data & GIS Services, 226 Perkins http://bit.ly/190FS13
2. 2. Data Visualization http://guides.library.duke.edu/datavis/
3. 3. What is Data Visualization? a general way of talking about anything that converts data sources into a visual representation (charts, graphs, maps, even just tables) http://guides.library.duke.edu/datavis
4. 4. Why Visualize? •  Explain complex concepts quickly and effectively Anscombe’s Quartet I II III IV x y x y x y x y 10.0 8.04 10.0 9.14 10.0 7.46 8.0 6.58 8.0 6.95 8.0 8.14 8.0 6.77 8.0 5.76 13.0 7.58 13.0 8.74 13.0 12.74 8.0 7.71 9.0 8.81 9.0 8.77 9.0 7.11 8.0 8.84 11.0 8.33 11.0 9.26 11.0 7.81 8.0 8.47 14.0 9.96 14.0 8.10 14.0 8.84 8.0 7.04 6.0 7.24 6.0 6.13 6.0 6.08 8.0 5.25 4.0 4.26 4.0 3.10 4.0 5.39 19.0 12.50 12.0 10.84 12.0 9.13 12.0 8.15 8.0 5.56 7.0 4.82 7.0 7.26 7.0 6.42 8.0 7.91 5.0 5.68 5.0 4.74 5.0 5.73 8.0 6.89 Property Value Mean of x 9 Variance of x 11 Mean of y 7.50 Variance of y 4.122 or 4.127 Correlation between x and y 0.816 Linear regression line (exact) (exact) (to 2 decimal places) (to 3 decimal places) (to 3 decimal places) y = 3.00 + 0.500x (to 2 and 3 decimal places, respectively) http://en.wikipedia.org/wiki/Anscombe%27s_quartet
5. 5. Why Visualize? •  Explain complex concepts quickly and effectively Anscombe’s Quartet http://en.wikipedia.org/wiki/Anscombe%27s_quartet
6. 6. Why Visualize? •  Translate something typically invisible into the visible http://blogs.library.duke.edu/data/2012/11/12/adding-colored-regions-to-excel-charts/
7. 7. Why Visualize? •  Use visuals to contextualize data, tell a story, or possibly even mobilize action around a problem Hans Rosling – The River of Myths http://www.youtube.com/watch?v=OwII-dwh-bk http://www.gapminder.org/
8. 8. CREATING A VISUALIZATION
9. 9. From Data to Graphic •  What data types are present in the data source? •  How are the variables likely to relate? •  What visualization type seems to be the best fit for the goal?

12. 12. Common Visualization Types Showing Time See LibGuide (http://guides.library.duke.edu/vis_types) for examples and tools.
13. 13. Common Visualization Types Showing Numbers See LibGuide (http://guides.library.duke.edu/vis_types) for examples and tools.
14. 14. Common Visualization Types Showing Relationships See LibGuide (http://guides.library.duke.edu/vis_types) for examples and tools.
