d3 = require("d3@6")
random = Math.random()
Math.round(random)
Math.floor(random)
md` ## Some key points about \`Math\`
- \`Math.random()\` will generate random numbers less than 1.0.
- If \`random = 8.9999\`, then \`Math.round(random) = 9 \` but \`Math.floor(random) = 8\`.
- \`Math\` is **parallel** with \`d3\`, so \`d3.Math....\` is unnecessary and wrong.
`
md`## Task 8
- 8-7. Let the dataset be made up of 50 pairs of random numbers between 0 and 100 that are integers.
- 8-8. Remove labels.
- 8-9. Treat values on x-axis as percentages with one decimal point precision. *Hint* : using \`d3.format("")\`, and \`.tickFormat()\`.
`
md`# Chapter 9: Updates, Transiations, and Motion`
md` Task 9-1.
- 9-1-1. Make a normal-looking bar chart for this dataset: [ 5, 10, 13, 19, 21, 25, 22, 18, 15, 13, 11, 12, 15, 20, 18, 17, 16, 18, 23, 25 ]. Width and height of the SVG: 600, 250.

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.
