Air Traffic Demographics of Passenger Count vs Year (2011-2019)
This grouped bar chart shows monthly passenger counts for domestic and international flights departing San Francisco International Airport from September 2011 to September 2019, with blue and coral bars representing the two flight categories across a shared timeline. The visualization loads data from a CSV file, sorts entries chronologically, and uses `d3.nest()` to group rows by parsed date. It employs `d3.scaleBand()` for the x-axis, `d3.scaleLinear()` for the y-axis, and `d3.axisBottom`, `d3.axisLeft` to render axes. Data originates from DataSF, with the chart rendered as SVG with CSS-styled bar rectangles.

The above scatter plot shows the passenger count boarding to flights from the San Francisco International Airport over a period of 9 years. The data is from September, 2011 to September, 2019. Instead of showing aggregate passenger count for a year, they are plotted for every month. The passenger count per month is also separated based on the type of flight they are boarding, i.e. "Domestic" or "International".
Here the blue circles represents the passenger count for international flights, and the red circles represents the passengers count for domestic flights, per month.
The farther the circle, from x-axis (Year) the more number of passengers boarded that flight type.
