This bar chart shows Airbnb’s annual revenue from 2015 to 2019, increasing from roughly $0.9 billion to $4.8 billion. The visualization uses D3 v5 with an SVG rendering approach, applying `scaleLinear` for the revenue axis and `scaleBand` for the categorical years. Revenue values from the CSV are multiplied by 1000 and formatted with abbreviations using `format('.2s')`. Axes are built with `axisBottom` and `axisLeft`, while gridlines and labels are styled via CSS classes. The data originates from Airbnb’s pre-IPO S-1 filing.
