This example demonstrates how to load and parse an external CSV file using D3.js (v7) and render the data as an interactive SVG visualization. The code fetches a comma-separated dataset asynchronously, uses d3.csv to parse it into JavaScript objects, and then binds the resulting array to SVG elements for display. The rendering emphasizes the pipeline from raw data to visual marks, with axes, scales, and gridlines derived from the parsed values. The example is minimal and instructional, showing the complete flow from file loading to DOM generation in an SVG context.
