Get use of FREE template for connection circle
Explanation about relationship circles is in the book Connection (chapter 8)
It states what relationship circles are and what the intention and method are. There are also many examples.
Drawing connection circles yourself, writing your own words in them and drawing arrows by hand is certainly preferable to digital connection circles. However, it is sometimes good to have a digital version. Such a digital connection circle is easy to create with Office. For many, Word and PowerPoint is available for free. This makes creating a digital connection circle relatively easy. You can use THIS model to help you on your way. ( Also take a look at the tips on the second page of that PowerPoint.)
