This visualization displays a bar chart of digital skill levels across European Union country groupings for 2015, with each bar representing a different country category and its length corresponding to the percentage of individuals with specific skills. The chart uses D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the y-axis, rendering SVG rectangles. Data is loaded from a CSV file with `d3.csv`, and values are parsed as numbers before being mapped to bar widths. The code relies on `d3.select`, `max`, and `scaleBand` to structure the visualization.
