Hi, I’m Swizec Teller. Over the years I've helped over 10,000 engineers hone their craft. 

With React+D3v4 you'll learn the basics of building fast data visualization components in about an hour. Get started immediately without installing anything.

I based React+D3v4 on 20 years of experience with learning how to code on my own, reading blogs and articles, listening to professors, and working with mentors.

Don't know React? React+D3v4 starts at the very beginning.

Struggling with D3? Every function is explained.

I bought your course Because D3.js is highly flexible, and writing a bunch of method chaining sucks for D3

I'm a react veteran who has always wanted to learn D3. I know enough about it to know there will be some quirks integrating with react, so figured your book would save me and my team from having to figure those out on our own. 

I use React because it is the sane way of doing things. I use D3 because I have to. I want nice interactive charts. I want to stay sane.

In my old age, I love having practical examples to help me learn new things faster.

D3's docs alone are okay but marrying them with React (as a react newbie) is not as straightforward as someone handholding you through the process. And, since I don't have hours after work or on weekends to hack on things like I used to before I was married (or had kids), I need to optimize my learning.

I already owned your previous version and know it would be worth my money to buy the updated version.

Thanks for all of the hard work!

Become a data visualization engineer with React + D3v4

It's an interactive visualization app with a choropleth map and a histogram comparing tech salaries with median household income in the area. Users can filter by three different parameters – year, job title, and US state – to get a more detailed view.

It's going to be great.

At this point, I assume you've used `create-react-app` to set up your environment. Check the [getting started](https://www.educative.io/collection/page/10370001/5710051981393920/5642489998344192/) section if you haven't. I'll also assume you've read the [basics chapter](https://www.educative.io/collection/page/10370001/5710051981393920/5632965908365312/). I'm still going to explain what we're doing, but knowing the basics helps.

I suggest you follow along, keep `npm start` running, and watch your visualization change in real time as you code. It's rewarding as hell.

If you get stuck, you can use my [react-d3js-step-by-step Github repo](https://github.com/Swizec/react-d3js-step-by-step) to jump between steps. The [9 tags](https://github.com/Swizec/react-d3js-step-by-step/releases) correspond to the code at the end of each step. Download the first tag and run `npm install` to skip the initial setup.

If you want to see how this project evolved over 22 months, check [the original repo](https://github.com/Swizec/h1b-software-salaries). The [create-react-app](https://github.com/Swizec/h1b-software-salaries/tree/create-react-app) branch has the code you're about to build.
