md`Functions and methods are the same, basically. They take in our codes and give us outputs.
\`D3\` is an object. We need to reference it first before we can access its functions, like \`select\`, \`append()\` and \`text()\`.
Scott was using \`append("p")\`. I tried to replace \`"p"\` with anything I liked, and they also worked. Try yourself. **I don't know why they worked, though.**
