Configuration

When deploying a fork that points at a different data repository, update the BASE_URL constant near the top of src/plots.js:

const BASE_URL = "https://raw.githubusercontent.com/myorg/myrepo/main";

Development

npm install
npm run dev

Tests

npm test                   # unit tests (Vitest, in jsdom)
npm run test:coverage      # the same, with a coverage report
npm run test:e2e           # integration tests (Playwright, in Chromium)
npm run test:visual        # screenshot comparison of the map against committed baselines

The unit tests cover the page's entry module (src/plots.ts) as well as its helpers: tests/unit/plots-harness.ts loads the page's markup into jsdom, stands in for Plotly and for the network, and drives the page through its controls. Coverage from both the unit and the integration tests is reported to Codecov; to see what the integration tests exercise in the browser, run npm run test:e2e:coverage and then npm run coverage:integration.
