The data shown here comes from Flight Delay Analysis Dataset

This chart meant to show the "Percentage of flights delayed w.r.t Departure for each origin airport". The color saturation denotes the percentage of delayed flights that belong to each airport. The tooltip shows the percentage delay w.r.t total delay at all airports, when you hover over it.

The questions that can be asked from this chart are:

• Which airport had the maximum delayed flights? Ans = ORD
• What percentage of flights were delayed at the airport DFW? Ans = 9.8%
• How many airports have a delay percent of 3% or above? Also, what are those airports? Ans = 4, ORD, DFW, DEN, LGA
