Gem takes a hash as input which includes information about code:

• methods names
• number of arguments
• method length (lines of code)
• number of conditions inside a method

Based on supplied data gem renders svg file with a "dude" that has:

• N hands (N - number of methods)
• each hand has Y fingers (Y - number of arguments)
• "muscles" (number of conditions in method)

If method length is higher than a predermined value then arm will be longer than normal.

The following hash will produce a figure presented below:

object = { name: "ThingCollection",
  :methods=>
   [{ name: :initialize, args: 3, length: 2, conditions: 0 },
    { name: :all_types, args: 0, length: 6, conditions: 2 },
    { name: :one_type_things, args: 6, length: 9, conditions: 0 },
    { name: :one_thing_by_type, args: 2, length: 9, conditions: 0 },
    { name: :weather_clothing, args: 4, length: 10, conditions: 0 },
    { name: :message, args: 1, length: 6, conditions: 1 },
    { name: :signal, args: 5, length: 10, conditions: 4 }] }
