I'm interested to understand more about what people are doing in the open data arena (ref: http://theodi.org/guides/what-open-data ) and related topics such as visualisation and big data tools (client and server side).

It would be great to hear more about how Drupal has played a part in this or how it interacts with related tools.

We recently experimented by creating a tool that uses the data about the last 5000 commits to D8 - https://www.deeson.co.uk/drupal8r
