This chart displays electronic sales totals over time as a single black line, with a sky-blue background and labeled axes. The visualization uses D3 version 5, reading a CSV data source and parsing date strings with the `d3.timeParse` API. It maps years to the x-axis using a time scale (`d3.scaleTime`) and total sales to the y-axis with a linear scale. The line is drawn using the `d3.line` generator, and axes include grid lines and rotated axis labels.
