This example visualizes historical Bitcoin price data alongside moon phase information, displaying daily high values in text form with a message header. The code loads a CSV file containing Bitcoin’s open, high, low, close, and volume data with moon phase annotations using d3.csv, then iterates through the parsed rows to log each day’s high price to the console. The visualization relies on React’s useEffect hook to asynchronously fetch and process the data, while the container div is styled with a gray background. No chart or graphical rendering is implemented; the focus remains on data parsing and textual output.
