This bar chart displays the population of the top 10 most populous Chinese provinces, based on 2018 estimates from the United Nations World Population Prospects. It demonstrates extensive D3 axis customization, including custom tick formatting that converts large numbers to abbreviated labels, grid lines, and styled tick text. Using d3.scaleLinear and d3.scaleBand, the chart positions bars and applies d3.axisLeft and d3.axisBottom with modified tick behavior. The SVG rendering includes a title, axis label, and steelblue bars, with data loaded from a CSV file.
