Bowtie risk diagram Barrier-based risk management — one hazard's top event (the knot) with threats fanning in through preventative barriers on the left and consequences fanning out through mitigative barriers on the right, the whole shaped like a bow tie.
Matrix / quadrant 2×2 / 3×3 / N×M matrix diagrams (Eisenhower, BCG, heatmap).
Mindmap Radial or markmap-style mindmap from markdown headings.
