My go-to plotting method is Plotly, which generates amazing, interactive* figures in 3D and 2D. The resulting figures are either hosted on Plotly's web page, or in the form of an HTML file on your computer which you can open in any browser**.
When you upload a plot to chart studio, you can easily share a link to that figure. They also provide you with embed ...
Sandcastle is Cesium's IDE-in-a-webpage where people can test their code and visualize the results.
One of the recommended ways to use the ...
NIX doesn't really exist any more. It was one of the many redundant image sites NASA had, specifically one hosted at Langley. It used to look like this.
(internet archive link)
Note that the weblink today doesn't go anywhere.
I haven't tested them all, but results found through checking the NIX option on ntrs generally result in broken links.
(Extended from comment.)
I think the question boils down to: do we want to answer trivial questions or not. Both direction has some dangers.
Disadvantages of making them off-topic:
It would cause that many good-standing layman newbies would be expelled from the site.
We will have much lower visit count.
Furthermore, some like an "inner circle" ...
I understand the sentiment and concern but before adding more features to the site let's do our homework.
What existing, documented problem that could not be addressed with existing tools would now be solved with the proposed solution? (the single example cited was easily and quickly handled with current tools)
How many examples of this problem can be cited ...
Since you can code in Python, I suggest taking a look at SageMath which is built on top of Python, and can do various 2D plotting (via matplotlib) & interactive 3D plotting. It's not perfect, but it does have an interesting feature: small Sage scripts can be encoded into a URL that runs on a SageMathCell server, so they don't have to be hosted anywhere.
I stopped participating in Space.SE three months ago, because another user said he would no longer answer my questions because he felt I already knew the answers.
So if you don't do any research, some say your question doesn't belong here. But if you have done the research, your question also doesn't belong here. Damned if you don't, damned if you do.
According to NASA itself,
The NASA Image eXchange (NIX) is a web-based search engine for simultaneously searching one or more of NASA's online image and photo collections.
As the saying goes, a picture is worth a thousand words, so they might be helpful (if you can't find an appropriate picture in any other way). But YMMV ...

A series of monographs from the 1970s covering many aspects of rocket propulsion system design. (There may be other entries in the series that I have not located.) All are .pdfs from NASA NTRS.
