Creating maps the right way with R and D3

Sep 13, 2018 · London, United Kingdom

This month we'll be learning how to create our own geogrid maps using the R programming language and the D3 data visualisation library.

Maps showing data such as how parliamentary constituencies voted can be challenging as different areas have radically different sizes but all count equally (https://twitter.com/treyyingst/status/862669407868391424). However the way the data varies over different areas can also be an important part of the story. An alternative to a typical map is to create a geogrid map like the ones in this piece (https://medium.com/@urbsmedia/the-london-housing-shortage-its-simple-maths-70fe7fd7c769) that instead use consistent shapes such as squares or hexagons.

We'll be learning how to produce our own geomaps from data using the R programming language, and then visualising that data using D3 and Javascript.

The tutorial is being written by Martín González (https://twitter.com/martgnz), visual journalist at the Economist.

Bring a laptop along as this is a practical, hands-on workshop. No programming experience is required. However, if you feel comfortable doing so, please install R (https://cran.rstudio.com/) and R Studio (https://www.rstudio.com/products/rstudio/download/#download). If you have trouble doing that, don't worry, we will help you on the day.

Please make sure you're signed up to Dropbox to view our shared doc (https://bit.ly/journocoders-sep-2018) — and add links to anything data or journalism-related you've seen or worked on to the show and tell section!
