Vector Graphics, what are they?

Explanation

Vector is a new type of graphic compression for the World Wide Web. Take a look at the images below to get an idea of why Vector is so powerful.

This dot was drawn in Photoshop. At 100% it still looks crisp and perfectly round.

Once this same dot is blown up to 700% (or x7) the image loses its crispness, and looks jagged. That's because Photoshop tells the computer that you need a certain amount of pixels to create an image.

Look at the image above, see the blown up squares? each one of those is its own pixel.
