This bar chart displays the percentage completion of road construction projects in Argentina, using data from a semicolon-separated CSV file. The visualization encodes project names on the x-axis and their advancement percentage on the y-axis, with bars representing each project’s progress. Built with D3 v5, the code uses `d3.scaleBand` and `d3.scaleLinear` to position bars, `d3.axisLeft` with a custom percentage formatter, and `d3.dsv` to parse the data. The SVG rendering includes rotated axis labels and a simplified y-axis without domain lines.
