This dashboard visualizes student AI usage patterns through four coordinated D3 charts. A pie chart shows the proportion of students using AI, a bar chart compares average grade improvement across AI tools, a scatter plot explores study hours versus grade change, and a line chart displays average grades before and after AI use across student ages. The visualization uses d3.csv to load the students_ai_usage_cleaned dataset, d3.rollup for aggregation, d3.scaleOrdinal for categorical coloring, and SVG rendering with a custom tooltip for interactivity. All charts respond to hover events using the showTooltip and hideTooltip functions.
