This visualization compares individual students’ subject scores with the average score for each favorite subject. Orange bars animate upward from zero on load, while sky-blue bars overlay the average per subject; hovering turns bars red with a tooltip showing the exact score. Built with D3 v7, it uses `d3.text` to load tab-separated data, `d3.rollup` to compute means, and `scaleBand`/`scaleLinear` for axes. The SVG renders with transitions, axis labels, and rotating x-axis text.
