Gruff can be embedded in any web page to let readers use Gruff on your web site. The file embedding.html in the Gruff installation folder explains how to set up a running example of this. That file also serves as the example web page itself. You can adapt its JavaScript code for use on your own web site.
Gruff needs to be running in a special "launcher" mode on a server machine that the web browser can reach. Then your web page can send a message to the Gruff server that tells it to launch another instance of Gruff for the reader to use in one area of your page.
Simply embedding Gruff allows the reader to use Gruff by itself as usual inside the web page. A more advanced feature is that your web application can also send custom commands to Gruff. For example, your application could derive a set of triples that it wants Gruff to display, and then send those triples to Gruff.
See embedding.html for the actual example file that you can find in your Gruff installation folder. Note that its "Run Gruff Below" button will not work here, because the Gruff server is not running.
This example requires Gruff 8.1.0 to fully work as described here.
Below are a couple of images of the example web page as it appears in a browser after Gruff has been embedded in an iframe below the instructions. The drop-down widget above Gruff contains custom commands that the web page sends to Gruff.
