Dev Notes

Dependencies:

• d3: Data-driven documents

Dev Dependencies:

• Typescript: Uhm... Typescript, yeah
• mocha: Unit testing framework
• chai: A BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.
• c8: Code Coverage
• ts-node: A TypeScript execution engine and REPL for Node.js. It JIT transforms TypeScript into JavaScript, enabling you to directly execute TypeScript on Node.js without precompiling. Is used by mocha.
• tsup: Bundle your TypeScript library with no config, powered by esbuild.
• @types
