International tourist arrivals by world region since 1950 (Millions)

The visualisation shows how tourist arrivals have increased since shortly after the Second World War in 1950. The scatter plot presents this data. The value of every point represents each data while the color represents the region it belongs to.

This scatter plot was forked from curran's block: Stylized Scatter Plot with Color Legend. Data from Our World in Data "Tourism in Global Connections" by Max Roser.
