Wow, this is incredible. The entity relationship example http://gojs.net/latest/samples/entityRelationship.html http://gojs.net/latest/samples/entityRelationship.html is dia quality. great stuff!

Very cool! What are your plans for licensing this if someone wanted to build it into their product?
- simonsarris 14y ago
  It will be sold as a standard commercial license and licensed per domain, with support and updates included for the duration of a term. The details aren't final yet, though.

Looks very similar to MxGraph (http://www.jgraph.com/mxgraph.html http://www.jgraph.com/mxgraph.html). Would be interesting in seeing a list of what features it provides that MxGraph doesn't.

Sort of a bum out wrt to the license. If I read it right it is free only for evaluation but not for use in your own product ala MIT? What is the pricing model then?
- simonsarris 14y ago
  The pricing model is based on number of developers, number of app (domains) used, and length of support/update subscription. Pricing figures aren't final, but they won't be aimed at hobbyists, probably closer to Sencha's ExtJS prices.

Wow that is a great implementation! Fantastic work guys. edit: bug report: "View this sample page's source" link at http://gojs.net/latest/samples/entityRelationship.html http://gojs.net/latest/samples/entityRelationship.html calls JS that goes to URL of "view-source:http://gojs.net/latest/samples/entityRelationship.html http://gojs.net/latest/samples/entityRelationship.html, the "view-source:" at the beginning prevents it from connecting.

  Sorry! I forgot about this issue. view-source: is a convenience protocol only supported by Google Chrome and Firefox, which makes the source look nice (syntax highlighted). When I have time I'll make an appropriate alternative for other browsers.

What about turning the cursor to a hand when hovering on reactive elements?
- simonsarris 14y ago
  Totally doable, but up to the programmer if they want that functionality or not. In the library it's as simple as setting a GraphObject's cursor: 'pointer' The only sample I can think of that has that functionality is this one: http://www.gojs.net/latest/samples/basic.html http://www.gojs.net/latest/samples/basic.html In the above example it is set only on the colored shape to indicate that it is possible to create a new link if dragged from the edges of a node.

Reminds me of old Java applets. Very nice work
