This column chart displays yearly values from a CSV file, with year on the x-axis and value on the y-axis. The bars are rendered as SVG rectangles using D3 v5's `scaleBand` and `scaleLinear` for axes, with `d3.axisBottom` and `d3.axisLeft` providing tick labels. The chart is interactive, showing tooltips on mouseover and triggering an alert on click, using data from `data.csv`.
