Write it out

Careful — pressing this builds the chart again from the text.

This browser is not allowing storage (a private window, perhaps). Drawing and exporting still work.

Rules for writing it out

  1. One line, one box. They follow each other in the order you write them.
  2. A line ending in a question mark splits. The lines indented under it are the branches.
  3. The next line after the branches is where they meet again.

Wrap a line in brackets for a start or end shape, and put ‘yes:’ in front to name an arrow.

Page 1280 × 896 The dashed line is the page edge. Drag its bottom-right corner to resize. Copying as an image and saving as SVG trim to the drawing itself; anything past the page edge is left out.

Double-click a box (or press F2) to edit its text in place. Drag to move; select one and drag a corner to resize. Drag on blank canvas to select several, then use Align and Spacing above. Ctrl+C and Ctrl+V copy, Delete removes.

PNG blurs when enlarged. Save as SVG for slides — PowerPoint converts it to editable shapes.
