1 Census Data Visualization Gallery As Data For the Digital Government Strategy Dr. Brand Niemann Director and Senior Data Scientist Semantic Community AOL Government Blogger March 28,

2 Background Received about Data Visualization: Images That Tell a Story Webinar: – visualizations visualizations Referenced Data Visualization of the Week: – I Started to Build a Census Data Visualization Gallery as Data (Accessible to All) For the Digital Government Strategy: – I Heard the Webinar and Was Further Motivated to Respond to Their Invitation to Provide Comments: – visualizations visualizations 2

3 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. 3 Source: https://www.stephencovey.com/7habits/7habits-habit2.phphttps://www.stephencovey.com/7habits/7habits-habit2.php

75 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 75
