This bar chart displays yearly counts from a CSV dataset, with steel-blue rectangles representing each year’s value. The visualization uses D3 v5 to load and parse the data, then applies `scaleLinear` for the horizontal axis and `scaleBand` for vertical positioning. SVG elements are appended directly to the chart, with axes omitted from the final rendering. The bars scale in width according to the year values while maintaining equal heights for each band.
