Overview
Edward Tufte is a pioneer in the field of data visualization. His principles focus on maximizing the 'data-ink ratio' and minimizing 'chart junk' to ensure that the viewer's attention is focused entirely on the information.
Key Principles
- Data-Ink Ratio: Maximize the share of ink used to represent data vs. non-data elements (like borders or background patterns).
- Avoid Chart Junk: Eliminate unnecessary decorative elements that don't add information.
- Small Multiples: Using a series of similar charts to allow for easy comparison across different categories or time periods.
- Data Density: Aim for high information density without sacrificing clarity.
- Integrity: Ensure the visual representation accurately reflects the underlying numbers (avoiding 'lie factors').
