This bar chart displays the populations of ten countries, scaled by a factor of one hundred, using blue bars on an SVG canvas. The visualization is rendered with D3 v7 within a React framework, parsing the `data.csv` file via the `csv` function and loading it with `d3.select`. Bar positions and heights are calculated using `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with rectangles generated through the `join` method.
