When inserting a string that cannot be converted to a floating point number (e.g. 70,01 instead of 70.01), the mark is created and appears on the plot, but it not added to straditize.
Expected Output
Straditize should directly give an error to inform about the invalid number. Instead, this is printed to the terminal:
Terminal output
```
