This example shows a bar chart of example data from the d3-graph-gallery website, displaying one categorical value per country. The bars animate vertically with a staggered delay, and value labels fade in above each bar. The chart is built using D3 v7 with SVG rendering, using `scaleBand` and `scaleLinear` for scales, plus `axisBottom` and `axisLeft` for axes. Data is loaded via `csv` from a GitHub raw source, and the layout is managed by a custom spacing module.
