Background

This is my graduate final project for the Harvard University course on Visualization.

 

Since 9/11 the United States Army National Guard (ARNG) has seen a dramatic mobilization of units in support of Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF) Afghanistan/elsewhere, and other missions such as peacekeeping in Bosnia/Kosovo, various hurricanes for domestic service, US Border Patrol mission, and other missions such as the recent Presidential election.  Approximately 250,000 soldiers have mobilized from the ARNG for OIF and OEF operations alone. This visualization shows the total cumulative soldiers mobilized depicting each unit mobilized using their state/territory location of origin, size of unit in bubble format, and color coding based on mission destination of mobilization.  The visualization shows the total cumulative numbers of soldiers mobilized for each major mobilization destination category (Iraq, Afghanistan, Other) and in total for all, over the period of time from 9/11 to present.

 

Project Questions

Below is the list of my motivating questions and why I choose them.  The motivating questions served to drive the purpose and outcome of the visualization.

 

Timeline of Mobilizations.  What mobilizations have occurred for the ARNG since 9/11?

Reason for this question: The main visualization here is a timeline over which mobilizations have occurred, showing these as they occur over the timeline.  This virtualization would depict total cumulative soldiers mobilized as compared to other graphics that typically depict mobilized numbers at just one point, seeing that depiction shows a more broad picture of the impact of the mobilizations.

 

Pace of Mobilizations.  Has the momentum of mobilizations over time increased or decreased?  Has the pace of mobilizations increased or decreased taking into account total soldiers for each mobilization? 

Reason for this question: The answer to this question would show if the operations tempo has gone up overall or down overall over time, or are other patterns clear.

 

Types of Mobilizations.  What is the comparison between mobilization destinations (types) including Iraq, Afghanistan, and Other types of mobilizations. 

Reason for this question:  This will show a break-out between Iraq, Afghanistan, and Other types of mobilizations which will reveal which one is the main driver of ARNG soldier mobilizations.  While it may seem that Iraq should be the primary driver this may not be the case.

 

Timing of Mobilizations.  Is there a relationship between mobilizations and other major events?

Reason for this question: This will show if there were increased mobilizations around events such as “the troop surge”, US elections, calendar year ends, etc.  The timeline will show these events as they occur and the viewer can review if mobilizations have increased/spiked around these events.  Similar outcomes could related to decreased mobilizations.

 

Mobilization Destinations.  Is there any relationship between types of mobilizations, size of each? 

Reason for this question: This will show if there is some typical size mobilization in the ARNG, typical unit size, or does this vary.  This will also show if there is relationship between the numbers of soldiers mobilized at any time and certain events.

 

Total ARNG Force Size.  How does the numbers of soldiers mobilized from the ARNG over time compare to the total current force size of the ARNG? 

Reason for this question: It will be interesting to see if the numbers of soldiers mobilized over time is greater than the current entire size of the ARNG force.  This won’t mean that everyone in the ARNG has been mobilized, some soldiers have been mobilized two to three times and there have been soldiers coming into the ARNG and leaving the ARNG, but this would be an interesting review just in general.

 

Geography Trend.  Have there been geographic trends or concentrations for unit mobilizations?  For instance from various particular States/Territories. 

Reason for this question: This visualization could show if certain areas of the US have been harder hit by ARNG mobilizations versus other areas.

    Destinations – mobilization type keyed to legend colors

 

 

 

 

 

 

 

 

 

 

4.  State & Territory Matrix  (right side of the visualization)

 

    Matrix – all states and territories

    Data – units mobilized appear as bubbles by size / color code by  destination

    Mouse – can  see unit size and month

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

5.  Other Numerical Data & Stop/Start

 

    Pause/Play – icons allow user to stop/start program

    Current Month – appears in box as more granular link to timeline

    Legend – color codes for each destination type, also state matrix description box with details

    Totals – running count building along timeline of mobilizations and sum of soldiers mobilized, boxes for destination and all combined

    City List – running list along timeline, just for visual

Design Features

Here are details on the visualization and interaction methods I implemented.  This is in priority order.

 

Graphic/States, the original intention was to use a map of the US (States & Territories) as central screen.  Working with that showed that the map was overloaded with data bubbles so I opted for a matrix as a better option.

Reason for feature chosen: This is needed as the core part of the visualization, units as they are mobilized will be drawn as bubbles on the matrix in the appropriate State/Territory where they are based.

Implementation: This was implemented with the table containing the needed data used to pop bubbles on the screen into the appropriate state/territory box.  A mouse over of the bubble shows the number of soldiers mobilized and month mobilized.  The size of the bubble is based on the unit size and color is the destination of the mobilization as related to the key.

 

Time Progression, time will progress from 9/11/2001 to the present, will seek to allow the user to stop the timeline or jump around.

Reason for feature chosen: There will be a timeline on the top of the visualization that moves from left to right from 9/11 to present.  Other major events will show up above the timeline.

Implementation:  I was able to implement this as part of the process that draws the stacked mobilization destination counts.  Also under the timeline there appears a bar chart of total soldiers mobilized that month.   I researched and added major relevant events that could have impacts on unit mobilizations, for analysis.  The user is able to pause the timeline and start it again.

 

Unit Mobilizations & Size, as time progresses, units mobilized will appear in the state/territory matrix as bubbles with a size equal to the number of soldiers in the unit that were mobilized.  

Reason for feature chosen: This is a core portion of the visualization and shows mobilizations by location and also size. 

Implementation:  This was really a portion of the first design feature depicted above.  The almost animated view of the bubbles and sizes is useful for the viewer, for instance you see the surge of mobilizations to Iraq as all the green bubbles appear more rapidly.

 

Unit Mission Color Coding, units mobilized for Iraq will have a certain color, for Afghanistan another color, for Other missions another color.

Reason for feature chosen:  This will differentiate between the three groups of mobilization destinations visually.

Implementation:  Color.  I used the Color Brewer site to select the mobilization destination colors and the color for the combined data.  I wanted to avoid pure greens or blues or reds that might convey some form of status (good, poor, etc).  I opted for darker colors to be more distinctive.  This is used in all parts of the visualization and even in the charts that come up for more detail on each mission.

 

Mouse Over, a mouse-over will be done for the bubbles to see exact unit and number of soldiers mobilized.

Reason for feature chosen: The user can interact with the visualization in this manner to see what actual unit is being depicted and the number of soldiers from that unit mobilized.

Implementation:  This was implemented for the bubbles.  I also implemented a mouse over to bring up additional chart data for the mission destination types.  And the user can view additional state/territory data when they mouse over the city list.  The mouse overs (other than for the bubbles) pause the visualization to allow the user to review the information.

 

Bar Chart, across the left of the screen there will appear (and grow over the timeline) a bar chart with colors for mobilizations, showing colored portions of the bar for totals of soldiers mobilized from 9/11 to present in each destination category. 

Reason for feature chosen: This will be a running tally of count of each type of mobilization mission destination by month, color of the bar will link to the bubble colors and three mission destination areas.

Implementation:  I was able to implement this where the gap between each month is shown in white and the bars grow in sync with the timeline.  The viewer can see how the Iraq mobilizations start later but quickly ramp-up.

 

Pie Chart, a switch view option of the bar chart will exist to bring up a pie chart.

Reason for feature chosen: This is just another view as compared to the bar chart above.  Will most likely be another window.

Implementation:  I implemented this for the additional data view of the Other mission destination type since that was the one that really required another view.  This is done via a mouse over of the Other mission destination mobilization count and soldier sum tally boxes.

 

Data Table, off to the side of the screen that will update to show units, multiple deployments, totals by mission.

Reason for feature chosen:   This provides the raw data details over time, may need to be totals versus individual unit data due to the data set size. I may need to do this as another window.

Implementation:  I implemented this in the middle of the screen and I included a box that shows the totals/counts across all mobilizations as well.  I also put up a scrolling list of city locations, units mobilized.  That just serves to also show the pace of the mobilizations.
