Well, WolframAlpha (aka "online mathematica") surely qualifies as lightweight, has a bit of a learning curve and is by design easy to use, though it can misinterpret your input if you don't use the commands directly. It can certainly do everything a desktop calculator can. That said, it is unfortunately no longer free, and most of the cool advanced features (data analysis, etc..) are not available to guests...

 

You could use LaTeX/Tikz to draw polygons and possibly graphs, with no limitations, though the learning curve is quite punishing. You can then save and even share the text scripts everywhere. Not sure it qualifies as an "elementary tool" and it's not exactly lightweight, though I'm sure web services exist. But the "calculator" aspect is obviously lost, unless you are insane and want to use the preprocessor to compute stuff.
