This example loads the classic Iris dataset from a GitHub gist using d3.csv and logs each parsed row to the browser console. The page renders only a large static title and no visualization, highlighting data loading and parsing with D3 v7 in a React context. The code constructs the CSV URL by joining string fragments, then applies a parseRow function that currently returns the raw row unchanged. The example demonstrates a minimal setup for fetching and inspecting tabular data before any charting logic is added.
