This bar chart displays the absolute frequencies of six ordinal categories, such as "sehr gut" and "ungenügend," with a horizontal grid and y-axis label. Built with D3 v5, the visualization encodes values as bar heights and includes interactive hover transitions that enlarge the selected bar and show a tooltip with its category and value. The chart also renders data value labels above each bar and a divergence text (not implemented in the code). Axes are drawn using `d3.axisLeft` and `d3.axisBottom`, with scales from `d3.scaleLinear` and `d3.scaleBand`, while styling is applied via CSS classes.
