+This week we are exploring data from the [`roundabouts` package](https://github.com/EmilHvitfeldt/roundabouts) by Emil Hvitfeldt. 
+The roundabouts package provides a R friendly way to access the roundabouts database which is compiled by [Kittelson & Associates](https://roundabouts.kittelson.com/) 
+and contains information about the location, configuration, and construction of roundabout intersections around the world. 
+
+> “It started with an inventory of U.S. roundabouts that identified 150 sites,” Lee says. “One thing led to another, and now we’re at 
+over 20,000 records in the database.”
+
+- How has roundabout construction evolved over time? Are certain regions adopting them faster than others?
+- What types of intersections are most commonly converted to roundabouts?
+- Where are the roundabouts with the most unusual configurations (highest number of approaches/driveways)?

+    Hexagonal illustration of a roundabout with three cars circling around a central island. The circular island features four green trees or bushes arranged in a clover-like pattern. The cars include an orange car, a red car, and a yellow car. Gray roads with white dashed lane markings connect to the roundabout from multiple directions, surrounded by green grass areas. The word 'roundabouts' appears in yellow text on the road.
