Background• Received Email about Data Visualization: Images That Tell a
Story Webinar:– http://www.howto.gov/training/classes/creating-data-visualizatio
ns• Email Referenced Data Visualization of the Week:
– http://www.census.gov/dataviz/• I Started to Build a Census Data Visualization Gallery as Data
(Accessible to All) For the Digital Government Strategy:– http://semanticommunity.info/Census_Data_Visualization
• I Heard the Webinar and Was Further Motivated to Respond to Their Invitation to Provide Comments:– http://www.howto.gov/training/classes/creating-data-visualizatio
The 7 Habits of Highly Effective People Habit 2: Begin With The End In Mind
• Habit 2 is based on imagination--the ability to envision in your mind what you cannot at present see with your eyes. It is based on the principle that all things are created twice. There is a mental (first) creation, and a physical (second) creation. The physical creation follows the mental, just as a building follows a blueprint. If you don't make a conscious effort to visualize who you are and what you want in life, then you empower other people and circumstances to shape you and your life by default. It's about connecting again with your own uniqueness and then defining the personal, moral, and ethical guidelines within which you can most happily express and fulfill yourself. Begin with the End in Mind means to begin each day, task, or project with a clear vision of your desired direction and destination, and then continue by flexing your proactive muscles to make things happen.
• My Note: My End In Mind Is The Census Data Visualization Gallery As Data For the Digital Government Strategy.
My Comment: Visualization, Story, and MetadataAre Together, But not the Data Table.See Next Slide That Does That WithInteractivity Between Them and Makes DataAccessible to All!
My Note: See Data Sorted and Linked to Visualization!

Data Visualization Gallery• Population Bracketology• Migration Between California & Other States• U.S. Territory and Statehood Status• Spoken Languages Other than English• Center of Population, 1790-2010• Population Change by Decade• Without A High School Education• A Decade of State Population Change• State-to-State Migration• Population Under Age 5 by Congressional
District• Components of Metro Area Change• Blooming States• Largest Urbanized Areas• Coastline County Population• I-90 Population Density Profile, 2010• Keeping Pace with New York
• Population Shift to the West and South• I-10 Population Density Profile, 2010• Booming Cities, 1830-2010 (Previous
Example)• I-5 Population Density Profile, 2010• Islands of High Income• The Great Migration, 1910 to 1970• Following the Frontier Line, 1790 to 1890• Changing Ranks of States• State Populations: 1890, 1950, and 2010• Before and After 1940• Physical to Political Geography• Differential City Growth Patterns• I-95 Population Density Profile• Increasing Urbanization• Gaining and Losing Shares• Top 20 Cities

Population Change by Decade
http://www.census.gov/dataviz/visualizations/049/
My Comment: Small-multiples of County-level Maps are Difficult to See So a Few Maps with Say the Top 10 Population Changes and the Ability to Sort the Data is More Useful. Also Note the Large Number of Counties with No Data (Empty). See Next Slide.
My Note: See Visualization Labeled and Linked to Sorted Data!
My Story: This Trellis Chart Shows the Variation For Each of the Four Categories (Male and Female and Native and Foreign born) Across each Region by Race or Hispanic Origin and the Columns Can be Sorted in the Table Below to See Their Rank Order.

A Decade of State Population Change
http://www.census.gov/dataviz/visualizations/043/
My Comment: These Comparisons Require Lots of Eye Movement and An Extra Click toSee the Details for Each State. See Next Slide.
My Note: Use Filters and Sorting To See Links Between Visualization and Data.

Population by Congressional District
http://www.census.gov/dataviz/visualizations/034/
My Comment: I Would Use a Congressional District Map and a Statistical Distribution Function to Show These Data. The Data Set Was Augmented For That. See Next Slide.

Conclusions and Recommendations
• The Census Data Visualization Gallery Was Used As An Example of the Digital Government Strategy– All Content = Big Data.
• Spotfire Was Used to Make the Census Visualizations Statistical and Interactive.– Spotfire Was Originally Co-developed by Professor Ben Schneiderman,
University of Maryland, Who Developed the Treemap, Who Was a Consultant to the Census Bureau.
• I Responded to Their Invitation to Provide Comments.– Specifically, the Concept to “Keep focus on good visual ideas not cutting edge
interactivity” Should Be to Focus on Both and To Make the Data More Accessible and Complete. See Next Slide.
• The Census Flow Mapper-Beta is Next.– See http://flowsmapper.geo.census.gov/flowsmapper/flowsmapper.html
