A red line chart displays total electronic sales per year from 2001 to 2009. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` generators to render the SVG. Data comes from a CSV file loaded via `csv`, with the x-axis formatted using `d3.timeParse`. Gridlines and axis labels for "years" and "totalsales" support readability.
