This line chart shows the number of passengers flown by Qatar Airways from 2011 to 2021. The x-axis encodes years while the y-axis maps passenger counts, with a single maroon line tracing the trend over time. The visualization uses d3.scaleTime and d3.scaleLinear to map data, d3.axisBottom and d3.axisLeft for axes, and d3.line to generate the path. Data is loaded via d3.csv from a GitHub gist, with dates parsed using d3.timeParse. The SVG is rendered with grid lines and styled axis labels.
