Quadrant chart (Mermaid)

A quadrant chart is a way of forcing a prioritisation conversation. Naming the quadrants is what turns it from a scatter plot into an argument.


#What this example shows

  • Named quadrants, so nobody reads their own meaning into the corners.

  • Axis labels that state the direction of each scale.

  • Points positioned from 0 to 1 on both axes.

#Making it your own

  • Positions are opinions. Record who placed them and revisit afterwards.

  • Rename the quadrants to suit your own framing; the defaults rarely fit.

  • Two axes only. A third dimension needs a bubble chart.
