Q: 14

SIMULATION

[Visualization and Reporting]

The director of operations at a power company needs data to help identify where company resources

should be allocated in order to monitor activity for outages and restoration of power in the entire

state. Specifically, the director wants to see the following:

* County outages

* Status

* Overall trend of outages

INSTRUCTIONS:

Please, select each visualization to fit the appropriate space on the dashboard and choose an appropriate color scheme. Once you have selected all visualizations, please, select the appropriate titles and labels, if applicable. Titles and labels may be used more than once.

Your Answer

Correct Answer:

BASED ON THE SIMULATION'S REQUIREMENTS, THE DASHBOARD SHOULD BE CONFIGURED AS FOLLOWS:

DASHBOARD TITLE: POWER OUTAGES ENTERPRISE-WIDE
THEME OPTIONS: [ANY SELECTION IS VALID, E.G., RED (DEFAULT)]
VISUALIZATION 1 (TOP-LEFT - "COUNTY OUTAGES"):

CHART: THE MAP CHART (TOP-RIGHT OPTION).
TITLE: GEOGRAPHIC AREA OF OUTAGES
LABEL: COUNTY

VISUALIZATION 2 (BOTTOM-LEFT - "STATUS"):

CHART: THE GROUPED BAR CHART (MIDDLE-LEFT OPTION).
TITLE: STATUS OF INCIDENTS BY COUNTY
LABEL (Y-AXIS): NUMBER OF INCIDENTS
LABEL (X-AXIS): COUNTY

VISUALIZATION 3 (BOTTOM-RIGHT - "NUMBER OF OUTAGES FOR THE QUARTER"):

CHART: THE PIE CHART (TOP-LEFT OPTION).
TITLE: POWER OUTAGES IN THE QUARTER
LABEL (LEGEND): COUNTY

Explanation

The configuration aligns data visualization best practices with the dashboard's requirements.

The "Power Outages Enterprise-wide" title matches the director's need to monitor the "entire state."
For "County Outages," a map is the most effective visualization for displaying data distributed across a geographic area.
For "Status," the grouped bar chart is ideal as it allows for the comparison of categorical data (Closed, In Progress, Reported) across multiple groups (Counties).
For "Number of Outages for the Quarter," the pie chart is used to represent a part-to-whole relationship, showing how the total quarterly outages are distributed among the counties.

Reference: In the section "Visualizations in Power BI reports," Microsoft documentation guides the use of "Maps" for spatial data, "Bar charts" for comparing values across categories, and "Pie charts" for showing the relationship of parts to a whole. This supports the selection of the map for counties, the bar chart for status, and the pie chart for the quarterly breakdown.

Reference: Academic principles of information visualization emphasize selecting a visual encoding that matches the user's task. The task "identify where... resources should be allocated" (geographic) is directly supported by a map. The task of monitoring "status" (comparison) is supported by a bar chart.
