I can get a rough graph between cousins using a workaround in the experimental Consanguinity gramplet by @ukulelehans Hans Boldt.
Start by creating a temporary family with the cousins as ‘partners’. In the following example with the British royal family, I created a Family with Queen Elizabeth II and her 2nd cousin once removed, Alice of Battenberg. (The cousin graph could have been illustrated with the existing marriage to Philip. They are 3rd cousins. But that wouldn’t demonstrate the use of a temporary family.)
The Relationship in the Spousal consanguinity tab (in Notebook mode) describes the distances and removes. graph shows the diagram. Clicking that Relationship description will graph.
