Interactive implementations live in explorers/. The regression diagnostics explorer is built from explorers/regression-diagnostics.jsx into explorers/regression-diagnostics.bundle.js.
npm install
npm run buildRun npm run build after editing explorers/regression-diagnostics.jsx. The generated bundle is committed so the site can still be deployed as static files.
