Understanding Dynamic Graphics

It's important to evaluate the specific needs of a project to determine if it stands to gain functionality or efficiency from using dynamic graphics.

Dynamic graphics are graphics that are generated on the fly (meaning they are generated upon their rendering, not beforehand), typically by combining quantitative data with graphical imagery. A good example of a dynamic graphic is a bar graph that is rendered when it is loaded based upon ever-changing numeric data. Dynamic graphics are different from standard graphics in that they aren't stored in static files, such as .gif or .jpg files. Rather, they exist as a pairing of graphic content and data that merge together to form a final image. This image can be changed by modifying the data and refreshing/ republishing the image.
