This bar chart displays the number of entries per country from a CSV file with date records. It uses D3 v5’s `csv` loader, `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `axisLeft`/`axisBottom` to render the axes. The SVG rendering filters the data to China, Indonesia, and Russia, counting matching rows for each bar, which are styled with steelblue fill.
