 * Loading JSON Data to retrieve JSON data via URL section of code originally by Daniel Shiffman.  
 * code modified by AliaK to create a drawing from tezos api data 20-21/03/2021
 * modified sketch from 2019 version to change to tezos api
 * note: the api chosen below uses JSONArray not JSONObject (original 2019 sketch uses JSONObject) due to different format JSON source
 * this is a static version - it gathers the api data once then saves a jpg file of the api drawing
