This line chart shows the number of Walmart stores in the US over the last ten years, with years on the x-axis and store counts on the y-axis. The visualization is rendered as an SVG using D3 v5, employing `scaleTime` for the temporal axis, `scaleLinear` for the count axis, and `line` to generate the path. The chart includes labeled axes, grid lines, and a bold orange line, with data parsed from a CSV file using `csv` and `timeParse`. The styling uses custom CSS for tick labels, axis text, and the line’s appearance.
