This November, the Rbanism community takes part in the #30DayMapChallenge for the third time. Every day of the month has its own theme (from Points and Lines to Borgesian map and Pen & paper), and participants make a map or visualization for it and share it on social media.

The Rbanism twist: all maps are made in R and published together with their code on our GitHub (see the 2024 and 2025 editions). There is no need to do all 30 days. Pick one or two themes that speak to you.

We kick off together on October 23 at the Faculty of Architecture, TU Delft (Berlagezaal 1, also on MS Teams), with lunch, a lecture by Mark Padgham, the challenge kick-off and the Urbex book club.
