Viz on Video [28]

Keynote speeches and tutorials from two recent data visualization and cartography events

August 30, 2016

For today’s edition of Viz on Video, we picked a few keynote speeches delivered at two recent events: FOSS4G‘s annual meeting (in Bonn, Germany, between August 24 and 26) and one of the latest PyData conferences for data scientists using Python (it happened in San Francisco, from August 12 – 14).

In both cases, there’s a ton of new videos available. FOSS4G is the annual global event of the Open Source Geospatial Foundation (OSGeo), so the majority of the talks covered issues related to cartography and map-making tools, while PyData conferences bring together users and developers of data analysis tools to share ideas and learn from each other. During the events, the PyData community gathers to discuss how best to apply Python tools, as well as tools using R and Julia, to meet evolving challenges in data management, processing, analytics, and visualization.

In this talk, Christopher Roach discusses what a map projection is, and why the Mercator projection, the map you use everyday, is both incorrect and unfair, but useful nonetheless. He also does a walkthrough on some ways that we can create maps using Python.


This tutorial by Stephen F. Elston and Ronald Lopez introduced attendees to the most commonly used Python visualization packages, matplotlib, pandas plotting and seaborn.


The Human Rights Data Analysis Group (HRDAG) uses methods from statistics and computer science to quantify mass violence. As part of that work, we rely on open source tools, including python and R, for data processing, management, analysis, and visualization. Megan Price, Executive Director of HRDAG, highlights how the organization uses those tools to estimate how many people have been killed in the ongoing conflict in Syria.

We hope you enjoyed this selection of videos. Next week, we’ll return with more. And don’t forget to check out the video section of our infographic gallery.
