This bar chart visualizes the scores of different teams using D3.js (v7) with SVG rendering. It loads CSV data from a GitHub gist and maps team names to the y-axis with a band scale, while a linear scale positions the bar widths based on score values. The code uses `d3.csv`, `scaleBand`, `scaleLinear`, and `axisLeft`/`axisBottom` to construct the chart, with red rectangles and styled text. Axes and margins frame the visualization, which updates dynamically after parsing and converting the numeric score data.
