Generation, analysis and visualization of reticular ornaments using Gavrog, now coming to a browser near you.
The most recent stable version can be found at http://gavrog.org/webGavrog.
To play with the source code:
git clone https://github.com/odf/webGavrog.git
npm install
npm run build-dev
Then open the file dist/index.html in the browser.
If that does not work, try starting a local web server on the dist directory, e.g.
(cd dist && python -m SimpleHTTPServer 8000)
Then use the URL localhost:8000 in the browser.
