This chart shows the total number of students grouped by gender, with blue bars for males and red bars for females. It uses the d3.csv method to load the dataset, then d3.rollups to count occurrences per gender before mapping values to bars. The visualization is rendered as SVG, with d3.scaleBand and d3.scaleLinear for positioning, plus interactive tooltips triggered by mouseover events. Data comes from the provided dataset.csv file, which includes academic and demographic records.
