With SEBG you can push asynchronous commands to a browser window.
For example, the following three Erlang commands:
Pid ! {eval, "document.body.innerHTML='';"},
Pid ! {eval, "document.body.style.backgroundColor='red';"},
Pid ! {eval, "document.body.innerHTML+='<h1>Hello World</h1>'"},
Will erase all content on the current web page. Make page red and say hello world.
The web page runs a universal script. It waits for message containing Javascript, then evaluates it and waits for the next message.
Look in drag4.svg and svg_test.html. At the top of svg_test.html I have some outstanding problems. Try to fix these.
