Man Writes Data Structure on Clear Surface

A man wearing a white collared shirt uses a black marker to write 'Data Structure' on a clear surface. The shot is a mid shot of the man's torso, and his hand holding the marker is also in focus. The background is a plain, light background. This video could be used in corporate, educational, and technological projects. The words the man writes are relevant for science, technology, engineering, and math educational projects.
