representing it visually

At a recent party at my house, I overheard two people, who hadn't known one another previously, begin an animated conversation over their shared enthusiasm for carpentry and table-making. There were so many people who didn't know each other. I am always wanting to introduce people and particularly those with overlapping areas of interest. I began a kind of Venn diagram on the chalk board in my kitchen of people and the things they liked, experiences they'd had, qualities they possessed. Then I let everyone else take it over. (pictured here) 

I would not describe this as a functional image, necessarily. No doubt there are far more elegant and scannable ways of displaying the same content visually. But it was a lot of fun to make and to puzzle out later. I've dubbed it a disinformation graphic, which is amusing but not quite apt. Perhaps a hermeneutic circle of a party? I'll accept suggestions.
