The New York Public Library is making available for download a vast collection of restaurant menus. Here are some visualizations of this data.
Simple maps of the Menuverse: it shows menu-pages (blue dots) and their dishes (white dots). As the numbers grow the Menuverse becomes more nebulous and interconnected, no dish is alone.
The next images show if menu pages share a dish. When running it over a small number of dishes the Menuverse has a well-defined structure but soon it all curls up again into a big knot. This I tried to overcome by tweaking the parameters. Later images connect the menu pages only if they share at least 10 or even 25 recipes.
These images show what type of ingredients are matched with what other types as reported by the name of dish. It is color-coded (meat, dairy, vegetables, alcoholic drinks).
