This bar chart displays the number of confirmed cases across nine Chinese provinces, using horizontal bars sorted by province name on the y-axis and a linear scale for case counts on the x-axis. The visualization is rendered as an SVG using D3 v5, with `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the chart and axes. The data is loaded from a local CSV file via `d3.csv`, and the bars are drawn as `rect` elements with a steelblue fill. The example highlights axis customization and margin-based layout for a clean, labeled presentation.
