Dynamically generated graphics
Explanation:
The term "Dynamic generated graphic" refers to simulate movement, motion, or generating a specific environment using the computer. It can also be thought of as multiple plots associated with time. Hence the graphics generated in the dynamic manner from the real time data utilize the huge part of the CPU cycles.
