Working off Marc Syp's video idea I've created my own version. It's a little more clunky, but it gets the job done. It all starts from my excel file where I've listed program names and then areas. These are imported through the plug-in

Ghowl to Grasshopper. In grasshopper you have to manually list which items should be attracted to what. My file has a bunch of adjacency requirements, then a few off site requirements I've tried to communicate in my diagram. This is where list-item grabs the appropriate areas and attracts them to each other. The example is for an elementary school.

Next I've set surfaces in rhino for attraction. This example is for a vertical elementary school, so for example views were important for certain rooms. With Marc's program, they all tend towards a sphere themselves. For more vertical designs, I've added a core attractor surface to draw the bubbles vertically. This can definitely be refined, but I wanted to share it asap to all those people waiting for Marc to share something. All in all it's basically a simple sphere packing script I found and adapted to suit architectural purposes. 

Here's a video of it in action
