About data-driven graphics
Data-driven graphics make it possible to produce multiple versions of an image quickly and accurately. Let's say, for example, that you need to produce 500 different Web banners based on the same template. In the past, you had to manually populate the template with data (images, text, and so on). With data-driven graphics, you can quickly generate Web banners using variables and data sets.
You can turn any image into a template for data-driven graphics by defining variables for layers in the image. In addition, you can create different sets of variable data to view what your template will look like when it is rendered.
Creating different versions of an image using variables A. Source file template B. User defines layers as variables C. Different versions of the image can be created, each with a different variable data set
