javascript-d3How do I create a tutorial using JavaScript and D3?

Creating a tutorial using JavaScript and D3 is easy and straightforward.

To begin, create an HTML page with the basic elements such as a <head> and <body> tag.
Include the D3 library by using the <script> tag and linking to the CDN.
```
<script src="https://d3js.org/d3.v5.min.js"></script>
```
Create a <div> element with an id attribute to contain the tutorial content.
```
<div id="tutorial-container"></div>
```
Use JavaScript to create a new D3 selection that uses the #tutorial-container id as the selector.
```
let tutorialContainer = d3.select("#tutorial-container");
```
Use the selection to add elements to the page. For example, to create an <h1> element, use the append() method.
```
tutorialContainer.append("h1").text("My Tutorial");
```
Repeat step 5 to add more elements to the page.
To style the elements, use the style() method to set the css properties.
```
tutorialContainer.select("h1").style("color", "blue");
```

My Tutorial (in blue color)
