This example visualizes the placement status of students from a CSV dataset using D3.js. The data is loaded and parsed with `d3.csv`, then summarized with file size, row count, and column count displayed as text. A pie chart rendered in SVG compares the percentage of placed versus unplaced students, using `d3.pie` and `d3.arc` with distinct colors and percentage labels. The visualization demonstrates loading, parsing, and aggregating CSV data, followed by a simple categorical comparison via a donut-style pie chart.
