Grading Criteria

Keys and values are clearly labeled

Each key has exactly one arrow pointing to its value

All three key-value pairs from the prompt are included

Boxes or shapes are used to represent keys and values

Arrows or lines correctly connect keys to their values

Solution

  +---------+       +-------+
  |  Apple  | ----> |  Red  |
  +---------+       +-------+

  +----------+      +---------+
  |  Banana  | ----> | Yellow |
  +----------+      +---------+

  +---------+       +---------+
  |  Grape  | ----> | Purple  |
  +---------+       +---------+

This diagram shows a dictionary with three key-value pairs. Each key (fruit name) is inside a box on the left. An arrow points from each key to its value (color) on the right. This visually represents how a dictionary stores data: each key is linked to a specific value.

For example, the key "Apple" points to the value "Red", meaning the color of an apple is red. Similarly, "Banana" points to "Yellow", and "Grape" points to "Purple".

Variations - 2 Challenges

[intermediate] Draw a diagram for a dictionary storing four countries as keys and their capitals as values: France - Paris, Japan - Tokyo, Brazil - Brasília, Canada - Ottawa.

[advanced] Draw a flowchart that shows how to look up a value in a dictionary given a key. Use the example dictionary: Dog - Bark, Cat - Meow, Cow - Moo.
