This example loads a CSV file containing sales, profit, and customer data across four regions from 2018–2023, then parses the numeric columns with `d3.csv` and `forEach`. It shows a raw data-loading stage with parsed values logged to the browser console, serving as a preliminary step for further visualization. The code uses D3 v7 for CSV parsing and data type coercion, with React providing the component structure via a simple import map setup.
