Visualization or visualisation (see spelling differences) is any technique for creating images, diagrams, or  animations to communicate a message. Visualization through visual imagery has been an effective way  to communicate both abstract and concrete ideas since the dawn of humanity. Examples from history  include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary  methods of technical drawing for engineering and scientific purposes.

Visualization today has ever-expanding applications in science, education, engineering (e.g., product  visualization), interactive multimedia, medicine, etc. Typical of a visualization application is the field of  computer graphics. The invention of computer graphics may be the most important development in  visualization since the invention of central perspective in the Renaissance period. The development of  animation also helped advance visualization.

Data visualization is the graphical representation of information and data. By using visual elements like  charts, graphs, and maps, data visualization tools provide an accessible way to see and understand  trends, outliers, and patterns in data.

In the world of Big Data, data visualization tools and technologies are essential to analyze massive  amounts of information and make data-driven
