This example displays a simple HTML page titled “ICE-5” that loads a CSV file of mammal data from a GitHub gist using the D3.js library’s `d3.csv` method. The code iterates through the parsed data, logging each mammal’s name and age to the browser’s console. The page’s visual output is a large static text message, while the dataset interaction takes place entirely in the background, with no charts or graphical elements rendered. The styling and layout rely on plain CSS embedded in the document head.
