This bar chart example loads population data from a CSV file with d3.csv and renders a static set of rectangles using D3’s selection and data-join methods. The code imports `select` and `csv` from D3 v5, appends a group element to an SVG, and binds the dataset to `rect` elements with fixed width and height attributes. The visualization displays each country’s population values from the 2022 column, though the chart does not scale the bars to the data values and only logs the country names and populations to the console.
