This horizontal bar chart displays the population of Chinese provinces and municipalities for 2019, using steel-blue bars sorted by administrative region. The data comes from the National Bureau of Statistics of China, loaded via a CSV file. Built with D3 v5, the visualization uses `scaleLinear` for the population axis, `scaleBand` for categorical province labels, and `axisBottom`/`axisLeft` to render gridlines and ticks. The chart title and axis labels are added as SVG text elements, with tick formatting converting numbers to millions.
