About this quiz

What you’ll practice

You’ll learn to choose chart types that fit the question, the data shape, and the audience—so your visuals explain rather than confuse.

Each question gives 4 options and there’s no timer, so you can think through trade-offs like readability, scale, and message clarity.

Difficulty and quiz setup

Difficulty is mixed on purpose: easier items cover classic matches (bar for comparison, line for time), while tougher ones test edge cases (stacked vs grouped, log scales, small multiples).

You can select how many questions to play and choose a difficulty level before starting, making it easy to do a quick warm-up or a full practice run.

Common pitfalls to avoid

Using pie charts for many categories or tiny differences
Mixing too many variables in one chart without clear encoding
Truncating axes or inconsistent scales that mislead comparisons
Choosing a line chart for non-ordered categories
Overusing 3D effects, heavy gridlines, or cluttered labels

Tips to improve fast

Focus on the task first (compare, rank, trend, part-to-whole, distribution, correlation), then pick the simplest chart that answers it cleanly. When in doubt, prioritize readability and consistent scales over novelty.
