The New York Public Library is making available for download a vast collection of restaurant menus. Here are some visualizations I done of this data. At full size the images are clearer but these are the cropped ones. Another set of images maps historic mushroom use.
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) but I forgot by what code.
