This chart displays Amazon’s annual net income from 1994 to 2020 as a red line across a time-series. The x-axis encodes years, while the y-axis shows income in millions. D3 v5’s `d3.csv`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` generate the SVG path, with `d3.axisBottom` and `d3.axisLeft` producing labeled axes and gridlines. The data is loaded from a GitHub gist and parsed using `d3.timeParse`.
