cheminformatics - How do I make 3d molecular graphics similar to those shown on Wikipedia?

I want to make 3d molecular graphics similar to those found on Wikipedia. In the page for benzene, you can see the structure looks like this:

However, if I go to the interactive image as shown in here:

I get an interactive image that looks like this:

To me, the second image doesn't look nice, and I prefer the first one. However, I cant seem to find a way to get the image of first type for any molecule after converting from SMILES. I want to draw the structure of, say for example, Bismabenzene? How do I produce a graphical image for that if it's not available on Wikipedia?

Answer

Have a look at Molcalc. It's fully online and uses JSmol as a visualiser.

Alternatively you can browse the Pitt Quantum Repository for structures that have already been calculated.
