Exercise

Encoding data in color & size

In this exercise, you'll visualize the relationships between the prices of organic and conventional avocados.

The following NumPy arrays are in your workspace:

  • conventional_price contains the month-by-month average price of conventional avocados in numerous markets.
  • organic_price contains the same for organic avocados.
  • fraction_organic contains the fraction of avocados sold in the month that were organic.

You'll use matplotlib to try to answer a few questions and gain some insight into the market for organic avocados.

  • When conventional avocados cost more, do the prices go up on organic avocados, too?
  • When the premium for organic avocados is less, do people buy more organic avocados?
