This example shows the total sales of electronic products over time as a line chart. The chart plots sales figures against years, with a clean, sky-blue background and black line strokes for readability. The visualization is built using D3 version 5, leveraging the library’s scale functions (`scaleTime`, `scaleLinear`), axis generators (`axisBottom`, `axisLeft`), and the `line` generator to create the path. Data is loaded from a CSV file hosted on a GitHub gist, parsed, and rendered as an SVG graphic with custom styling defined in an external stylesheet.
