This example shows CPU utilization per minute for a server, displayed as a vertical bar chart where each bar represents one timestamp and its height reflects CPU percentage on a fixed 0–100 scale. The SVG rendering uses D3 v6 utilities including `csv` for data loading, `utcParse` and `utcFormat` for date handling, `scaleBand` for the x-axis, and `scaleLinear` for the y-axis. Axes are drawn with `axisLeft` and `axisTop`, while bars are appended as `rect` elements, with styling defined in an external stylesheet.
