As an analyst for the airline industry, you track the number of passengers at the top six major U.S. airports: Atlanta (ATL), Chicago (ORD), Los Angeles (LAX), Dallas/Fort Worth (DFW), Denver (DEN), and New York (JFK). You researched passenger data and created a worksheet that lists the number of total yearly passengers. You will create various charts—clustered column, bar, line, pie, and combo charts—and visualizations like sparklines to compare passenger traffic at these airports over multiple years, focusing on trends and specific data highlights. The steps involve creating, customizing, and formatting each chart to effectively communicate the passenger data, including adjusting axes, adding data labels, applying styles, inserting alt text for accessibility, and setting page layouts.

In this analysis, the passenger traffic data of the top six United States airports provides critical insights into air travel trends over recent years. These airports—Atlanta (ATL), Chicago (ORD), Los Angeles (LAX), Dallas/Fort Worth (DFW), Denver (DEN), and New York (JFK)—are among the busiest in the country, making their passenger counts valuable indicators for the airline industry. Through a comprehensive visualization approach, this paper explores the passenger data using various charts to illustrate overall traffic patterns, yearly trends, recent year comparisons, and individual airport performances over time.

Initially, a clustered column chart was created to compare the total passenger counts across these airports over a span of several years. This chart, positioned strategically at cell A15, was customized with a descriptive title, styled with Chart Style 7, and designed for clarity by swapping data series and categories. The value axis was adjusted to display data in millions, and the axis was labeled accordingly to improve readability. Emphasis was added to the 2019 data series by inserting data labels above each column, highlighting the passenger count for that specific year. A gradient fill background added visual appeal, and Alt Text was provided to improve accessibility, stating: “The column chart displays the number of passengers at top U.S. airports over several years”.

Next, a bar chart focused solely on the passenger counts in 2019 was constructed to allow direct comparison among airports during that year. The chart, moved to a dedicated chart sheet titled "Bar Chart", employed a monochromatic palette and style 5 for clear differentiation. Axis modifications included setting the maximum bound to 110 million and enlarging font sizes for readability. The Atlanta airport’s bar was formatted with a dark blue fill to highlight its leading passenger traffic. Additional gridlines (primary minor vertical) enhanced visual guidance, emphasizing differences among airports with immediate clarity.

A line chart was then developed to visually depict trends of passenger counts over time for the six airports. Situated on the "Line Chart" sheet, this chart displayed passenger trends from 2014 through 2023, with axes scaled to bounds of 40 million (minimum) and 110 million (maximum). The vertical axis displayed data in millions, and the legend was repositioned at the top for better visibility. To streamline the data presentation, only data from odd-numbered years was included, focusing on the most recent trends. The chart title, “Passengers at U.S. Airports,” was bolded, with axes labeled in a legible font size, and Alt Text was added for accessibility—“The line chart displays trends for top six U.S. airports”.

Sparkline visualizations offered a compact, in-cell graphical summary of passenger trends for each airport over the ten-year period. Inserted in cells adjacent to the data columns, the sparklines utilized blue as their color scheme, with high and low points highlighted to accentuate fluctuations. This compact visualization aids quick interpretation of consistent or volatile traffic patterns at each airport, providing an immediate sense of variations over the years.

Finally, page layout adjustments on the worksheet, including setting paper size to Legal, switching to Landscape orientation, applying balanced left and right margins (0.3 inches each), and scaling the content to fit on one page, ensured the report’s professional presentation. These formatting choices facilitate effective printing and sharing of the analysis.

Overall, this multi-faceted visualization approach enables stakeholders to grasp comprehensive passenger trends at the top U.S. airports. The combination of bar, column, line, pie, and sparkline charts, alongside meticulous formatting and accessibility considerations, ensures the data’s interpretability and supports data-driven decision making in the airline industry. Future analyses might include predictive modeling or incorporating additional airports to refine understanding of market shifts and passenger behaviors.
