Crash running example

[Chryseus]

Tried the map of orion example from the website and it produces the following error:

  File "/home/james/chart/chart.py", line 23, in <module>

AttributeError: 'float' object has no attribute 'startswith'

It appears to have something to do with with bayer_labels, I tried turning it off which produces an image but there are many 'nan' labels:

• Starplot 0.20.1
• Python 3.13.12
• Matplotlib 3.10.8

Installed on Arch Linux, tried both system python venv and conda with same results, starplot setup has been run.

Thanks for reporting this! It seems to be something with the way Pandas 3+ infers data types, so I've got a release going out shortly (v0.20.2) that'll resolve the problem temporarily by restricting Pandas to v2.2.3 or lower.
