Last updated 2018 December 27

These tutorials address an older version of D3 (3.x) and will no longer be updated. See my book Interactive Data Visualization for the Web, 2nd Ed. to learn all about the current version of D3 (4.x).

Downloading D3

Start by creating a new folder for your project. Within that folder, I recommend creating a sub-folder called d3. Then download the latest version of d3.v3.js into that sub-folder. As of this writing, the current version of D3 is 3.4.2.

D3 is also provided in a “minified” version, d3.v3.min.js, from which whitespace has been removed for smaller file sizes and faster load times. The functionality is the same, but typically you’d use the regular version while working on a project (for friendlier debugging), and then switch to the minified version once you’ve launched the project publicly (for optimized load times). The choice is up to you, but in these tutorials we’ll be using the standard version.

A third option is to download the entire D3 repository, which gives you not just the JavaScript files, but also all of the component source code. You can browse the repository contents first, or just download the whole thing as a compressed ZIP file.

Referencing D3

Create a simple HTML page within your project folder named index.html. Your folder structure should now look something like this:

        d3.v3.min.js (optional)

Now paste the following into your HTML file, so it references D3 in the head and provides room for your JavaScript code:

<!DOCTYPE html>
<html lang="en">
        <meta charset="utf-8">
        <title>D3 Test</title>
        <script type="text/javascript" src="d3/d3.v3.js"></script>
        <script type="text/javascript">
            // Your beautiful D3 code will go here

Viewing Your Page

In some cases, you can just open your HTML file in a web browser to view it. However, when loading external data sources, it is more reliable to run a local web server and view your page from http://localhost:8888/. You could use a server like MAMP or see the notes on the wiki on activating a quick, temporary server.
