Make course flowcharts keyboard-navigable.
A prerequisite flowchart trapped in a PDF is invisible to screen readers and impossible to navigate by keyboard. Upload the chart and get an interactive prerequisite graph you can move through with the arrow keys — plus a text outline and a course-sequence table, all WCAG 2.2 AA.
Navigate by keyboard
Arrow keys move between courses; press P to jump to a prerequisite and U to a course it unlocks.
Built for screen readers
Every course announces its prerequisites, corequisites and what it unlocks. A full text outline mirrors the graph.
Faithful to the original
A layered prerequisite graph preserves the meaning of every arrow — and the course-sequence table comes along for the ride.
