14 graph types
Every graph in the statistics curriculum
Build dot plots and box & whisker, histograms and bar graphs, pie and donut charts, and scatter graphs with regression lines, correlation and residuals. Add time series with seasonal decomposition and forecasting when your students are ready for more.
Teaching inference
Animated tools that make inference click
Show sampling variability in motion. Watch confidence-interval coverage build up over many samples. Run bootstrap confidence intervals and re-randomisation tests live in class, so abstract ideas become something students can see.
Time series & forecasting
From trends to forecasts
Convert and encode time series, separate trend and seasonal effects with STL decomposition, and project ahead with a Holt-Winters forecast, all in a few clicks.

Common questions
Is KiwiGrapher really free?
Do students need to create an account?
No. Students just open app.kiwigrapher.com and start graphing. There's nothing to sign up for or install.
Where does the data go?
Nowhere. All calculations happen in the browser on the student's own device, so data is never uploaded to a server.
Is it aligned to NCEA?
Yes. KiwiGrapher is NZ-made and built around the graph types and inference methods used in NCEA statistics.
