Chooses visual cues and colors for purely aesthetic reasons without attention to data representation.
Chooses visual cues and colors that faithfully reflect the representation of the underlying data.
Data graphics are highly customized, and/or make use of a wide range of available geoms and color palettes.
Produces data graphics that are is unclear, confusing, devoid of context, or impossible to understand without reading the text.
Produces data graphics with readable axis labels, units, and legends (where appropriate).
Produces striking data graphics that tell a story, reveals the data, grab interest, and have low ink density per data density. Ideally, the viewer sees themselves in the graph.

Performs some operations manually in spreadsheet application.
Uses single table verbs to perform basic data wrangling and compute appropriate data summaries.
Optimizes wrangling code for readability and performance.
Relies on spreadsheet application, sorting, or manual reordering to merge tables.
Combines multiple data frames (tables) using *_join() functions and makes explicity mappings between variables.
Uses left, inner, and right joins intentionally to include or exclude potentially missing data.
Uses spreadsheet application or pivot tables to reshape data.
Transforms data frames from wide to long format and vice versa using pivot_longer() and pivot_wider()
Transforms data frames using list-columns and nest() and unnest().
Copies-and-pastes similar code three or more times.
