This example displays a bar chart of the number of files per year, with years on the y-axis and file counts on the x-axis. The visualization uses D3 v5 to load data from a CSV file, scale the values with `d3.scaleLinear` and `scaleBand`, and render SVG rectangles. Axes are drawn using `d3.axisLeft` and `d3.axisBottom`. The chart highlights the fluctuating file counts across years, peaking in 2014 and declining afterward.
