This visualization shows the percentage of individuals with various digital skills across different European Union country groupings in 2015, with each skill category represented as a horizontal bar. The data is loaded from a CSV file and rendered as an SVG bar chart using D3 v5. The code uses `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft` and `axisBottom` to display the axes. Each bar’s width is mapped to the percentage value, and the color is a fixed steelblue.
