Getting Viz.js

• Install the viz.js package from npm.
• Download from the releases page.

Building From Source

To build from source, first install the Emscripten SDK. You'll also need Node.js and Yarn.

Install the development dependencies using Yarn:

yarn install

The build process for Viz.js is split into two parts: building the Graphviz and Expat dependencies, and building the rendering script files and API.

make deps
make all

Running Browser Tests

The browser tests can be run locally using Selenium WebDriver.

First, serve the project directory at http://localhost:8000.

python -m SimpleHTTPServer

Then, run tests using test-browser/runner.js. For example, to run test-browser/full.html in Chrome:

node test-browser/runner --file full.html --browser chrome
