FYI for the input "Graph a cartoid and explain it" I get a correct definition and some interesting facts/properties (in spite of the fact that I mis-remembered the name of the object I had in mind; it should have been "cardioid"). But then it tries to provide a plot, and the plot has an error:
```
Error
Please check your input:
Undefined variable
heta
```
Looks like there's a "theta" that's being incorrectly truncated, or something to that effect.
I refreshed a few times and found that I consistently saw this same error.
