Sequential Function Chart

Question

Hello 
 Does anybody know how it would be possible to create sequential function charts or flow charts with DITA ? 
 Example (sorry it's in french)

Hi, I don't know of an easy way to do this in DITA. You would have to determine your DITA content model surrounding this and then have the publishing output render the sequential function chart. Not a trivial exercise. I suspect that the easiest way may be to create your chart in an external tool and save the chart as an image. That's just my opinion.
