Melan diagrams

Justin Alexander recently made several posts about the dungeon design methods seen in Paul Jaquays' adventures. Those articles are worth a read in themselves, and they use an interesting analytical technique which visualizes a dungeon as logical flowchart rather than a floorplan. I'm going to start making such flowcharts as a quality control measure after the first rough draft of my dungeons. (This reminds me of Stefanie Posavec's sentence drawings, which are worth a look if you're a fan if visualizations.)
