This visualization displays individual student subject scores as orange bars alongside skyblue bars representing the average score for each favorite subject. The bar chart animates upward on load using D3 transitions, with hover interactions changing bar color and showing a tooltip with the exact score. The code uses d3.text to load tab-separated data from a GitHub gist, d3.rollup to compute means, and d3.scaleBand with d3.axisBottom and d3.axisLeft to render the SVG chart.
