Need Custom SmartArt graphics for use in PowerPoint

The below link is the closest I have come to finding a 'tutorial' on how to create such designs and algorithms to work with SmartArt, but I need someone with the skills and, preferably, experience - https://docs.microsoft.com/en-us/archive/msdn-magazine/2007/february/create-custom-smartart-graphics-for-use-in-the-2007-office-system. There are 7-10 designs that need work (see attached).
