1. Tufte emphasizes that good data visualization should present complex information clearly and elegantly, making it accessible to the audience.
2. One key principle is to avoid chartjunk, which includes any decorative elements that do not enhance understanding of the data.
3. Tufte encourages the use of a high data-ink ratio, meaning that most of the ink used in a graphic should represent actual data rather than embellishments.
4. He also promotes the concept of layering information, allowing viewers to see both broad trends and finer details without overwhelming them.
5. Tufte's principles advocate for the use of small multiples to compare data across different contexts, which enhances pattern recognition and comprehension.
