Here is another network.

This time, it’s the characters in the book series Harry Potter.

The nodes in this network are individual characters, and the edges are their relationships. There are many different node types, to represent the different types of persons and animals, as well as various relationship types. The complete list is given in the legend, and is pretty self-explanatory.

Since the universe of Harry Potter is gigantic, I have only included information included in the seven books. Anything else, even if it is canon, is not shown. I know that there’s much more information available about ancestors of those characters, as well as their children in some cases. This is all not included. Note that the graph is already quite large and complex, and some edges go all over the place. Some persons are difficult to find too, because their placement may not be obvious. Since many characters have relationships to many other characters, there is not perfect layout for all of this. As a result, it is impossible to keep all groups of people together as one would like. For instance, it would be nice to have all members of the Order of the Phoenix in one block, and each family in one block, and all Hogwarts teachers in one block, but those all overlap, and I had to make choices. I hope the result is a good compromise.

Anyway, the network is also available as a PDF file, in which a text search can be performed.

To make the chart compact, I have omitted any titles like “Professor” and “Mr” in the names of people; you don’t have to notify me that the complete name of Nearly Headless Nick includes a “Sir” 🙂

I’m also aware that the overall layout is not perfect, but with a graph of this size, you have to make some tradeoffs, so I hope it’s still a very useful representation.

Another note: I know that there are differences between the books and the movies; this network is about the books.

As always, I’m happy about corrections, so please write about any error you see. (But keep in mind: I’m not adding info that’s only available outside the seven books.)

The actual PDF file had exactly double the size of A0. Apparently, there is no standardised name for this format (A−1?), but you could in principle print is as A0. In the PDF, each text box is 1 cm high.

Finally: This network contains spoilers for the Harry Potter series. Also, if you’re not familiar with Harry Potter, then you’ll probably find this all boring . . . .
