3 Dimensional Bar Chart

[yial2]

Hi guys,

I am new to D3. I went through the basic tutorial of bar chart and it
looked promising but far from what I am trying to accomplish. I need
to create 3D bar chart, something similar to this - "http://

.

The closest thing I can find on this group regarding 3D is "http://
groups.google.com/group/d3-js/browse_thread/thread/
92fda219410f0632/07f9b4692b6a1d91?lnk=gst&q=z+axis#07f9b4692b6a1d91".
I am not even sure if it is right to go with d3-js for this task. If
it is, can someone point me to some article/tutorial/information? Many
thanks!

There is more attempts at 3D with D3 here.

But frankly, SVG is maybe not the right technology for your task as 3D must be faked. WebGL could me more suitable (for example using PhiloGL), or a 3D wrapper like Threejs. But hey, who can resist extending D3 to all sort of challenges? 

Another concern is 3D bar charts are reputed very wrong, even an heresy in the Infovis community. For some reasons why, see for example a discussion on the subject in Tamara Munzner's upcoming book, section 3.5.

She is a very influential author in the field. But still 3D bar chart can be a fun thing to do in D3!
