Welcome





Overview of some exemplary plots included in my ggplot2 tutorial.

Animated evolution of a jitter-pop plot showing student-teacher ratios per continent. The animation shows iteration through different geometries, theme adjustments, combinations of layers, and additional annotations such as text labels with arrows and an inset tile grid map with colors by region mathing those of the main graphic.
