<human>:  Help me understand the Golden Ratio and its applications in art and design.
<bot>: The Golden Ratio, also known as the "divine proportion," is a ratio found in nature and architecture that is approximately equal to 1:1.618. This proportion is said to be aesthetically pleasing and has been used for centuries in art and design. It is found in the proportions of everything from the pyramids in Egypt to the Parthenon in Greece, and in architecture from the Renaissance to the Modern era. In art, artists can use the Golden Ratio to give the composition a certain balance and harmony. The ratio has also been linked to the concept of visual appeal in design, and many design elements, such as logos and websites, are constructed using the Golden Ratio.
