This bar chart displays the total score for several categories using vertical bars, with each category labeled on the x-axis and the numeric score on the y-axis. The data is loaded from a remote TSV file via `d3.tsv`, then processed and added to the SVG canvas. The chart is built with D3 v6, using `d3.scaleBand` for the categorical axis and `d3.scaleLinear` for the numeric axis, with bars drawn as SVG rectangles. Hovering over a bar changes its fill from steelblue to darkblue using CSS.
