This line chart visualizes annual sales data, displaying the trend of sales values over time on a red path. The SVG chart uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to construct the axes and line generator. It parses dates with `d3.timeParse` and loads data from an external CSV file. Grid lines are styled through tick marks, with blue tick labels and a rotated Y-axis label for clarity.
