This is a simulation question that requires you to create a dashboard with visualizations that meet the director's needs. Here are the steps to complete the task:
Drag and drop the visualization that shows the county outages on the top left space of the dashboard. This visualization is a map of the state with different colors indicating the number of outages in each county. You can choose any color scheme that suits your preference, but make sure that the colors are consistent and clear. For example, you can use a gradient of red to show the counties with more outages and green to show the counties with less outages.
Drag and drop the visualization that shows the status of the outages on the top right space of the dashboard. This visualization is a pie chart that shows the percentage of outages that are active, restored, or pending. You can choose any color scheme that suits your preference, but make sure that the colors are distinct and easy to identify. For example, you can use red for active, green for restored, and yellow for pending.
Drag and drop the visualization that shows the overall trend of outages on the bottom space of the dashboard. This visualization is a line graph that shows the number of outages over time. You can choose any color scheme that suits your preference, but make sure that the color is visible and contrasted with the background. For example, you can use blue for the line and white for the background.
Select appropriate titles and labels for each visualization. Titles and labels may be used more than once. For example, you can use ''County Outages'' as the title for the map, ''Status'' as the title for the pie chart, and ''Trend'' as the title for the line graph. You can also use ''County'', ''Number of Outages'', ''Active'', ''Restored'', ''Pending'', ''Time'', and ''Number of Outages'' as labels for the axes and legends of the visualizations.
