Effective visualization follows foundational principles designed to maximize clarity while minimizing "cognitive load" (the mental effort required to understand a chart). Why is Data Visualization so Important in Data Science
Data visualization is the art and science of transforming raw data into visual forms that human brains can interpret to support decision-making. Because the human brain processes visual information significantly faster than text—with some estimates suggesting up to 60,000 times faster—well-designed charts are essential for identifying trends, patterns, and outliers that would otherwise be lost in massive datasets. fundamentals of data visualization pdf download
