Consider the caffeine molecule skeletal formula as depicted in the Wikimedia Commons .svg file. Suppose that I want to replicate this skeletal formula with a high resolution and thicker lines.
I have found several online tools to draw molecules, but none of them allows the user to adjust line thickness (and, moreover, the resolution of the final output is generally not very high). I have also thought of using Tikz in LaTex, but going this route is really difficult and time-consuming, particularly if one wishes to replicate several skeletal formulae.
How would you draw a skeletal formula with thick lines and high resolution?
P.S: I’m sorry if this is not the correct place to ask such a question. If this is the case, feel free to tell me which SE site might be adequate for my question.
Thank you all very much for your time.
