@Arvind, yes, I believe the sort of functionality you describe is possible with Protovis because it is possible to associate a hyperlink with each of the nodes. Click on a done. Go to another URL.

I am looking for a different type of graphing where I wish to click on a logical node to reveal its inner content at the next level of hierarchy. Anyway this can be done with protovis?

Péter, thank you for checking, and yes, the visualization does not work with IE since Protovis creates SVG to render images, and IE does not support SVG. Alas. This is why I am hesitant to implement my network diagrams in my Alex Catalogue. (Sigh.)

Yes, now it is OK in both FF and Chrome in both Ubuntu and Windows XP. Except in IE8. It reported an “this object not supported this property of method” problem at protovis.js line 82 char. 261.

Resolved? After changing a Javascript line from:

force.label.add(pv.Label).font(’14px sans-serif’).textStyle(‘bold’);

to:

force.label.add(pv.Label).font(’14px sans-serif’);

the problem seems to have gone away on my part. Fixed?

I have tested it on Windows XC with Firefox, IE8 and Chrome. IE8 received and error, but other two browsers produced the same as on Ubuntu. “No label” means, that there are no labels displayed, but it displayed as a little popup when the mouse is over a node.

I have been able to verify this “bug”. ‘More later. I hope. Thank you.

Péter, other people have said the same thing. No labels. Weird. What browser are you using? I am using Safari on a Macintosh. WFM.

Eric,

when I see the examples none of the words appear as label, only the nodes and axes, while in your screeshot there are labels as well. The JS API would be interesting in using XC UI for facets or for visualizing subjects. Thank you for the post!

Péter
