This example displays a line chart of sales data over time, with the x-axis representing years and the y-axis representing sales figures. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` APIs to build the axes, while a `line` generator creates the orange stroke path. Data is loaded from a CSV file hosted on GitHub Gist, and the year values are parsed with `d3.timeParse` to format them as dates. The SVG rendering includes custom axis labels and styled tick marks.
