I just (re)discovered The Visual Thesaurus. Granted, they don’t have a large data set yet, but I think the spider diagram is actually a very effective representation…much better than the traditional Roget’s double look-up. Wonder how we could represent related recipes or similar chefs this way – am I too obsessed that this was my first thought?
