This line chart visualizes total sales of an Apple product from 2013 to 2022. It uses D3 v5 APIs such as `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to generate the SVG path, with gridlines from tick marks. The data is loaded from a CSV file hosted on GitHub Gist. The chart is rendered as an SVG element and uses updated date parsing to format the x-axis years.
