Facets. New open source visualization and data exploration tool from Google (“Disclaimer: This is not an official Google product”, whatever that means). It’s intended for visualizing machine learning datasets but it’s obviously useful outside of ML as well—any time you need to understand a large dataset this looks like it could be extremely useful. Ships with example jupyter notebooks and an easy mechanism for embedding the Facets interactive UI directly inside a notebook cell. # 8th October 2017, 12:21 am

The making of the NYT’s Netflix graphic. A database dump from Netflix, some clever hackery in ArcView GIS, hpricot to scrape Metacritic and a lot of careful thought about the UI for navigating the data. # 25th January 2010, 1:11 pm

russell davies: datadecs. Personalised christmas decorations made from data from Twitter, Doppler, and Flickr.

Best of all though is the Flickr decoration which represents the apertures you’ve used over the past year. # 7th January 2010, 9:58 pm for television. Dale Lane’s neat hack to visualise his television watching habits. An Ubuntu / vdx home theatre stores TV events in SQLite, and graphs are generated using Python and Open Flash Chart 2. The really clever bit: the back-end captures nearby bluetooth IDs’ allowing events to be filtered by the people watching based on the presence of their mobile phones. # 7th January 2010, 7:28 pm

Visualising Sorting Algorithms. Aldo Cortesi dislikes animations of sorting algorithms, so he designed a beautiful technique for statically visualising them instead (using Python and Cairo to generate the images). # 14th April 2009, 8:55 am
