 I'm pretty sure there's no code for doing it in character graphics
like in your image link!

 Something similar can be found in the R graph gallery:


 Or if you want an interactive spinny 3d-histogram, get the rgl
package and look at demo(hist3d). See:


 Those links should get you started. If you really do want ascii
character graphics...well, I think you're on your own....
