Using a choropleth map for county outages gives a quick visual of affected areas, and a line chart for trends clearly shows changes over time. For status, a horizontal bar chart could work well to compare categories side by side.
Using a map for county outages is definitely the way to go since it shows geographic spread clearly. For status, a stacked bar chart might be better than a pie chart because it’s easier to compare categories side by side. Line chart for trend makes sense since it highlights changes over time. For colors, I’d pick bold contrasting colors—like red for outages and green for restored—to make the status obvious at a glance. Keeping it simple but clear seems key here given the operational focus.
Map for counties, bar for status, and line for trend makes sense too.
I’d pick a heat map for county outages to quickly spot hotspots, a pie chart for status to easily compare proportions, and a line graph for the trend since it shows changes over time clearly. Colors should be distinct for clarity.
I’d start with a map visualization for county outages to see locations clearly. For status, maybe a bar chart showing active vs restored outages. A line chart would work best for overall trend of outages over time. Color scheme should use reds for outages and greens for restored to keep it intuitive. What do you think?
