title: How to use tqdm for JSON file load progress bar?
body: <p>I'm writing a Python script for JSON file processing. It's basically divided in three procedures: load, encoding and printing. While I've easily created progress bars for encoding and printing using tqdm, I can't figure out how to do it for load.</p>
  
  <p>I've thoroughly read tqdm docs and searched even here, but no clues</p>
  
  <pre><code>import json
  from tqdm import tqdm, trange
  from iso3166 import countries
  
  geo_json_events_path = r'/cygdrive/c/elastic/gtd.geojson'
  
  with open(geo_json_events_path) as f:
      data = json.load(f)
  </code></pre>
  
  <p>I expect the progress bar for <code>json.load()</code> method shown.</p>
