This project visualizes airline delays across various airports in the United States. The visualization includes a map that highlights delay data, with the size of the airport markers representing passenger flow.

• ax: The matplotlib axes object where the map and plots are drawn.
• time_slot: The specific time slot for which the delay data is visualized. It is an integer value.
• delay_type: The type of delay to be visualized. It can be 'dep' for departure delay or 'arr' for arrival delay.
• dropout_rate: The rate at which connections between airports are randomly dropped to reduce the density of the visualization. It is a float value between 0 and 1.
• od_delay: A dictionary where the keys are tuples of airport codes (source, destination) and the values are the total delay times between these airports.
• od_values: A list of delay values extracted from the od_delay dictionary.
• norm: A normalization object used to scale delay values for visualization.
• cmap: The colormap used for visualizing delays.
• sm: A scalar mappable object used for the color bar.
• cbar: The color bar object that provides a legend for the delay values.

Reads the number of passengers for a given airport code from a CSV file.

• Parameters: airport_code (str) - The IATA code of the airport.
• Returns: The number of passengers for the specified airport.

Plots the map with state boundaries, country boundaries, airport locations, and flight delay data.

• Parameters:

  • ax: The matplotlib axes object.
  • time_slot: The specific time slot for the delay data.
  • delay_type: The type of delay ('dep' or 'arr').
  • dropout_rate: The rate at which connections between airports are randomly dropped.

• Returns: The Basemap object.

Plots the airport locations on the map, with marker sizes representing passenger flow.

• Parameters:

  • ax: The matplotlib axes object.
  • map: The Basemap object.
  • s: The base size of the markers.
  • time_slot: The specific time slot for the delay data.
  • delay_type: The type of delay ('dep' or 'arr').
  • dep: Optional parameter for departure delay data.
  • arr: Optional parameter for arrival delay data.

• Returns: None.

Plots the connections (edges) between airports on the map, with colors and line widths representing delay times.

• Parameters:

  • ax: The matplotlib axes object.
  • map: The Basemap object.
  • od_delay: A dictionary of delay times between airport pairs.

• Returns: None.
