What’s the global data journalism community tweeting about this week? Our NodeXL #ddj mapping from Aug 6 to 12 finds @sciam profiling a new color scale for the color blind, @EDudinskij‘s fun dissertation on dataviz in science fiction movies, @morgenpost using satellite imagery to show the consequences of droughts, and @gregladen and Grant Foster calling bull on a climate change denier’s flawed graphs.
The Problem with Rainbow Color Scales
Data visualizations using rainbow color scales can sometimes be misleading and, for those with color blindness, are completely unintelligible. Now scientists at a US Department of Energy lab have developed a color scale — Cividis — that is mathematically optimized to be accurate for both color blind people and those with normal vision.
My Big Screen DataViz Dissertation
Here’s a fun dissertation idea by Edvin Dudinskij: analyzing incidences of data visualizations that appeared in science fiction movies.
Visualizing W.E.B Du Bois’ Black America
The colorful charts, graphs and maps presented at the 1900 Paris Exposition by famed sociologist and black rights activist W.E.B. Du Bois offered a view into the lives of African Americans, conveying a literal and figurative representation of “the color line.” Reserve your copy here.
Using Satellite Images to Show Drought
The consequences of the recent drought in Germany are very visible from space. See how Germany’s landscape has changed before and after the heat wave in this satellite-imagery piece from Berliner Morgenpost.
Climate Change: Tricking People with Bad Graphs
There’s a graph going around the internet from climate change denier Steve Goddard, aka Tony Heller, claiming to show that temperature in the US has been declining over the years. Both statistician Grant Foster and evolutionary biologist Greg Laden wrote blog posts calling bull on Goddard’s use of flawed data parameters to prove his point.
ICIJ’s Weapons of Choice
A look at the International Consortium of Investigative Journalists’ favorite data journalism tools, ranging from simple spreadsheets to software designed especially to tackle “big data” such as the #PanamaPapers and #ParadisePapers.
Significant DataViz Developments
Andy Kirk’s biannual round up of significant visualization developments is full of gems. This edition, covering the first half of 2018, includes data visualizations that are in the form of fun play-doh, that tackle important social issues and that showcase remarkable ingenuity.
Mapping Google Trends Data in R
Cognitive scientist Peer Christensen writes a short tutorial on how to get and visualize Google search data with both time and geographical components using the R packages gtrendsR, maps and ggplot2.
Free Mapping Course
Texas Tribune’s Darla Cameron and Chris Essig will teach a free online course on mapping for journalists from August 27 to September 23, organized by the Knight Center for Journalism in the Americas at the University of Texas.
Future of Journalism in Open Data
The second episode of Colombia’s Canal Trece #ElDato program focuses on taking advantage of open data to turn them into complete investigations. It highlights the data journalism work by La Silla Vacía and Connectas and speaks to journalists Claudia Báez and Mariana Santos about this journalism discipline.
