Vector graphics are those what are commonly known as "cartoons". Their composition consists of sharp lines and curves. These strokes are based on mathematical equations like the ones you learn in geometry and trigonometry classes. In short, for every vector object such as a circle or a square, there is a math equation associate with it. Because of this, these objects can easily scale up or down. That is to say, re-sizing them is easy. Just change the numerical values to the math equation and you get a larger and small version of the object.
By contrast, bitmap graphics are based on the pixel. Once the pixel density is determined, scaling the graphic distorts it. A photograph of a person's face is a bitmap graphic. If you enlarge it, the picture will become fuzzy because you artificially add additional information into it when there was none. In short, you make the computer guess what parts of the face look like up close.
The best known vector-based creator and editor is Adobe Illustrator. However, for its power, it is difficult to use and like all things Adobe, expensive. Luckily, if your need for vector graphic creation is simple like creating a logo or a sign or a graphic for your newsletter, there are plenty of alternatives that are either free of charge or less expensive than Illustrator. One such alternative does not even require you to install anything locally on your computer. One such product is called Method Draw. It uses the power of HTML5 to render the objects. HTML5 is efficient so using Method Draw is a joy, making you forget that this is not a program that you have installed locally on your computer. However, HTML5 does require the latest version of the web browser like Chrome and Firefox.

It takes a few hours to "master" Method Draw's techniques. If you are experienced in vector creation, you will able to create graphics using it in a mater of minutes because Method Draw uses the same principles as Illustrator and other vector-based creator programs.
