This bar chart displays population figures for the world’s most populous countries, with each rectangle sized by its corresponding population value from the included CSV file. The visualization uses D3 v5’s `csv` method to load the data and `selectAll` with data joins to append SVG `rect` elements to the page. Although the chart scales the rectangles to a fixed width and height, it does not yet map values to axes or a proper scale, leaving the bars as placeholders for a complete chart. The project relies on D3 utilities like `scalelinear` and the SVG rendering approach.
