playground · compose → validate → render → export

Build a curve. Take it anywhere.

Simulate a scenario with the in-browser Monte Carlo engine, start from a template, or paste a document from your own tooling. The reference validator checks every keystroke; the renderer redraws live; exports come out as JSON, standalone SVG, or a shareable link.

Poisson frequency × lognormal severity, seeded and deterministic — the same engine as openlec from riskquant. The document lands in the JSON tab; everything is derived from it.

Share links encode the whole document in the URL fragment — nothing is uploaded, and the link renders this exact chart for anyone who opens it.
