A horizontal bar chart displays the count of data entries per country from a CSV file, filtering for China, Indonesia, and Russia. The visualization uses a linear scale for bar widths and a band scale for vertical positioning, with axes rendered via `d3.axisLeft` and `d3.axisBottom`. The SVG is populated by `d3.select` and `d3.csv`, while `d3.max` sizes the scale domain. Bars are filled with steel blue, and the chart updates dynamically from the parsed dataset.
