A Vector-based graphical user interface (GUI) is a type of interface used on a computer or electronic device. It is made up of images and objects that are called "vectors". Vectors are drawn using lines and shapes, instead of pixels (like a photo). This type of interface makes it easier for you to use the device or computer and gives a more modern and polished look. You can move, resize, rotate, and change the color of the images and objects easily, making it much more interactive than other types of interfaces.
