TikZ fails to draw

Question

I'm trying to use TikZ to draw the following figure, I'm sure that the commands are correct but I obtain the following error:

"! Package pgfkeys Error: I do not know the key '/tikz/closed' and I am going to ignore it. Perhaps you misspelled it."

Can anyone help me with this problem?

Answer 1

After answering this, I discovered that the OP already got an answer to this question in the follow-up comments on Harish Kumar's answer to an earlier question. In fact, my answer below was perfectly well known to the OP. I'm not certain what the real question here is, but I'm sure it is not the one asked and which I answered.

[Perhaps the question should be, how can this be done without Hobby? Or perhaps it should be, how can I install Hobby? The second would be a duplicate unless there's some specific further problem, of course.]

There are two problems. The first is that you have not loaded the hobby library but are trying to use its options. The second is that you cannot use -- in curve through. See the Hobby manual for details.
