This dashboard displays a summary and preview of a Student Performance dataset, showing the first five students in a styled table and a bar chart of their GPAs. The D3.js v7 code loads CSV data via `d3.csv` and uses `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render the chart. A `<div>` message container reports dataset size, while the table uses CSS for zebra striping and hover effects.
