Dash: INTERACTIVE DATA VISUALIZATION WEB APPS WITH NO JAVASCRIPT

Please note the examples in this repository require Python >= 3.6 - official python 3.5 support is being withdrawn in January 2020...

The slides relating to this talk are available here: http://bit.ly/ep2019dash.

Example Applications

Run the apps in this repository to see how Dash can be used.

JGMTFC: Run Everything with Docker-compose

docker-compose -f docker-compose-talk.yml up

This will make the links on the slides work: http://bit.ly/ep2019dash

Install

This is a freeze of my environment in which all these worked.

pip install -r requirements.txt
