Not that I'm aware of. It's not that hard to draw flowcharts within InDesign (using the Align panel to align and distribute the shapes). But maybe an easier workflow would be to use a flowchart program that allows you to export the file into a format that you can place into InDesign.
Yes, of course it's possible to create the entire flowchart by hand with InDesign but the reason for me asking is to find an easy way of creating and editing flowcharts directly in InDesign. And that requires the dynamic placement of the lines...
Thanks for the link but I would rather stay inside of InDesign for the purpose of typography and overall design.
InDesign does not allow to place SVG directly.
You could open the SVG with Adobe Illustrator and place the AI file.
But you'll also have to deal with the RGB contents somehow.
Best to change RGB vekor paths to CMYK first in Illustrator if the output path is e.g. offset printing.
