This chart visualizes Amazon’s annual net income from 1994 to 2020 using a line graph. The SVG renders a time-based x-axis and a linear y-axis, with grid lines styled via CSS. The code imports specific D3 v5 modules (select, csv, scaleLinear, scaleTime, line, axisLeft, axisBottom) to load CSV data, parse year strings, and generate the path. Axis labels and tick formatting are added manually, while the line itself uses a stroke for emphasis. Data comes from a GitHub-hosted CSV file.
