As soon as I saw that character/faction/relationship map in BE I thought of a program we use at our school called Inspiration.
I’d like to recommend it for anyone who’d like to create a pristine chart. It’s a really handy brainstorming tool, and I love how you can switch seamlessly between the graphic presentation and the outline.
I used it in our own game to map out relations and the ability to manipulate the chart really helped me visualize the conflicts and issues at hand.
