A brochure with a few small graphs on the top of the page is not much of a challenge. But in this case the charts were made up of a data set, different for every location. This resulted in more than 3000 variations.
We created a workflow: Taking data from Excel, filtering the values automatically and creating a carefully structured XML file. This was then imported into Adobe Illustrator. From here a batch process exported the charts as a labeled .ai files.
