- 7-1-5. In \`var margin = ({top: 20, right: 30, bottom: 30, left: 40});\`, you **should not**, and in fact **cannot**, put \`;\` right after \`left:40\`.
- 8-1. \`g\` element is a \`group\` element. It is an SVG element, just like \`line\`, \`circle\`, and \`rect\`. One thing different is that \`g\` element is invisible. It serves two functions:
1. Helps us group other elements;
2. Accepts transformations onto it, which is very handy.
- 8-7. \`for (var i = 0; i < 50; i++){}\`. Two points to remember:
1. It should be \`var i = 0\`, rather than simply \`i = 0\`;
2. Seperate the codes inside the bracket by \`;\`, not \`,\`.
`
md`## Functions you absolutely have to call \`d3\` first:
- d3.scaleLinear() ...
- d3.max()
- d3.range()
- d3.easeLinear
`

- 9-1-2.
- It should be \`paddingInner()\`, rather than \`PaddingInner()\`.
- \`{return "rgb( )"}\`
- 9-1-3. \`.attr("text-anchor", "middle")\`
- 9-1-4. I should use \`d3.select("p")\`, rather than \`svg.select("p")\`. Why? Because the new \`p\` element is parallel with the \`svg\` element, I cannot select the \`p\` within \`svg\`.
- 9-1-5. The \`.transition()\` should be added within the anonymous function. It should be put after you have updated the data and before any changes.
- 9-1-8. It is \`ease(d3.easeLinear()\`, not \`ease(d3.scaleLinear())\`.
- 9-1-9. Scott Murray was wrong. The position of \`.delay()\` is not flexible at all. It mush be put AFTER \`.transition()\`.
`
md`
- 9-1-10. Please keep in mind that if you have \`.delay()\` after the \`.transition()\`, then \`duration()\` is applied to each individual transition, rather than all transitions in aggregate.
`
md`
- 9-1-11. Continue with 9-1-10. To scale the dynamic delay to the lenght of the dataset.

One platform to build and deploy the best data apps
Experiment and prototype by building visualizations in live JavaScript notebooks. Collaborate with your team and decide which concepts to build out.
Use Observable Framework to build data apps locally. Use data loaders to build in any language or library, including Python, SQL, and R.
Seamlessly deploy to Observable. Test before you ship, use automatic deploy-on-commit, and ensure your projects are always up-to-date.
