The tutorial code in the above documentation does not work properly, as if it was caused by this commit 0eac4d2.

Error details：
ValueError: Warning!  Given the WaveguideTemplate 'bend radius' and 'spacing' specified, no spiral can be fit within the requested 'width'.  Please increase the 'width'.

Hello! Thanks for pointing my attention to this. The documentation was, in fact, in need of updating. The issue with the Spiral waveguides was a result of some changes to the Spiral class implementation, so the documentation version was not accurate.

I've just pushed some changes to the documentation to correct this now, with proper Spiral instantiation as detailed here.
