This example loads a job placement CSV dataset using `d3.csv` and displays a summary of the data’s size, row count, and column count. It then calculates the number of placed versus unplaced students and renders a simple SVG pie chart with `d3.pie` and `d3.arc`, showing each category’s label and percentage. The chart uses an ordinal color scale and is styled with custom CSS in a React-compatible HTML page, though the interaction logic itself is plain JavaScript with D3 v7.
