The HTML contains its table, chart, text and comparison interaction. It starts a fresh student session without your practice answer. Editable JSON keeps the author's draft, including unfinished fields. Save it separately if you want to keep editing.

The editor keeps work in memory; closing or reloading can lose changes. Nothing is uploaded, synced or stored in an account. A file download is an explicit save.

AxisBridge supports one series of 2–12 non-negative whole-number quantities. It does not infer values from an image, explain causes or assess a student's learning. Its synthetic example is a demonstration, not a classroom study.

The table, native controls and comparison text are available without relying on a chart hover. Targeted keyboard and visual tests do not establish accessibility for every user or device. No screen-reader or teacher validation is claimed unless documented in the project evidence.
