## Where does the data come from?
We get
[publicly available PyPI download statistics](https://bigquery.cloud.google.com/table/bigquery-public-data:pypi.downloads)
on Google BigQuery using [pypinfo](https://github.com/ofek/pypinfo/).
[Here](https://github.com/pypa/linehaul-cloud-function) is the repo
for the open-source code pushing the pypi stats to BigQuery.
## Usage
First you need to get an access to PyPI's BigQuery, by following
[pypinfo](https://github.com/ofek/pypinfo/) procedure.
Then there's two main invocations, first fetch the data using:
python python-versions.py --fetch
Then plot it using:
python python-versions.py
