Terrible déception à Tahiti, je pensais tenir le jeu de mots du siècle quand... "Salon de coiffure / ÉPIcerie".
Oui, la requête est conçue pour collecter les noms avec "épi" dedans.

You can't beat Kyle Walker's {tigris} package for shapefiles and I love the shift_geometry() function to deal with the freak states, but this didn't quite work as planned for Census Regions #rstats #mapfail #notthedevelopersfault

Map of U.S. Census Regions made in {ggplot2} with shapefiles from the {tigris} package using the shift_geometry() function that didn't quite work as planned.

The USA really does know about the metric system and sometimes even plays with converting to it, as seen in this bit of map by the US Forest Service.

Day 13 of #MapFailbruaryChallenge "👀 Not colorblind friendly" #mapfail
For people without vision issue the map is pretty ugly, but they CAN see all information. Which is not the case for colorblinds. See QGIS previews for deuteranopia, protanopia and tritanopia.

French department of Drôme and its surrounding departements.
Chosen colors are problematic for colorblinds : they can not see difference between either the color of the departments label and the department color, the color of the point for the department prefectures and the department color or the title color and its background color.Simulation for Deuteranopia. Department prefectures are not visible.Simulation for Protanopia. The department names are not visible.Simulation for Tritanopia. Title is almost not visible, its color is too close to background color.
