D3.js Online Compiler / Playground

Write, test, and instantly preview D3.js data visualizations and SVG graphics online with our free Online D3.js Compiler / Playground. Experiment with data binding, DOM selections, scales, axes, charts, and dynamic SVG elements without installing packages or manually adding D3.js CDN links.

How to Use This D3.js Compiler

  1. Write or paste your D3.js code
    Enter HTML and JavaScript in the Code Editor. You can use D3 selections, datasets, SVG elements, scales, axes, transitions, and other supported D3.js APIs.
  2. Click the Run button
    Select Run to execute your code using the pre-loaded D3.js environment. Edit your data or visualization logic and run it again to test changes quickly.
  3. View the Output preview
    Check your rendered chart, SVG, or data-driven interface in the Output preview screen. Use the available copy, download, or delete controls while experimenting with different visualizations.

Key Features

  • Pre-Loaded D3.js Library: Start writing supported D3.js code without manually adding a CDN script.
  • Zero Installation: No Node.js, npm, bundler, or local D3.js setup required for supported examples.
  • SVG Rendering: Create circles, rectangles, lines, paths, text, and other SVG elements dynamically.
  • Data Binding: Practice D3’s data(), join(), and data-driven DOM manipulation.
  • Scales & Axes: Experiment with linear, band, time, and other supported scales.
  • Interactive Visualizations: Test events, transitions, hover effects, and dynamic updates.
  • DOM Selections: Use d3.select() and d3.selectAll() to manipulate page elements.
  • Custom HTML & CSS: Combine D3.js visualizations with regular HTML and your own styling.
  • Dark & Light Mode: Switch the Code Editor theme for comfortable development.
  • Instant Visual Preview: Click Run and immediately inspect the generated visualization.
1. How do I create a bar chart or SVG elements using D3.js here?

Start with an HTML container:

Then create an SVG and bind data to rectangle elements:

Click Run and the generated SVG bar chart will appear in the Output preview.

You can also create a basic SVG circle:

No. The playground is configured with D3.js library support, so supported D3 methods can be used without manually adding a CDN <script> tag.

For example:

For production projects, you should still install or load the D3.js version required by your actual application.

Yes. It is useful for learning and testing D3’s core concept of binding data to DOM or SVG elements.

D3 binds each array value to an <li> element and generates the list dynamically.

You can also update existing elements based on data:

Yes. Data binding and dynamic DOM manipulation are central features of D3.js.

You can also combine D3 with scales for data visualization:

The Online D3.js Compiler / Playground is useful for frontend developers, data visualization engineers, analysts, and students who want to practice D3 selections, data binding, SVG graphics, scales, charts, and interactive visualizations without setting up a complete local project.
