This example demonstrates how to load and parse external CSV data for use in a web-based visualization with D3.js. It shows a minimal HTML page that sets up the foundation for fetching tabular data and converting it into a JavaScript-usable format. The code relies on D3’s CSV parsing methods to handle the data ingestion process, though no visualization is rendered yet. The implementation focuses on the initial data-loading step, highlighting the API calls required to read and structure the dataset for subsequent graphical display.
