When reshuffling the lines of code to increase the ranks of some of the boxes, looks like there’s a missing line inside the subgraph, the one containing MA should be updated to:

MA-- "Makes API calls to\n[HTTPS]" --> WA

Otherwise the chart is not rendered as in the image

I’ve added some clarity to this, as the “moving the interaction” was before that, to show the ranks and how they work, but it needed to be put back in before extending the line lengths. It wasn’t at all clear though, so I’ve clarified.
