Missing dependency - alt.data_transformers

[sbabicki]

The line alt.data_transformers.enable("data_server") in tab1.py causes an error when I try to run it with the current environment file. I'm not sure what the dependency is called, but it needs to be added to the yaml file if we keep that line in.

Error I am getting:

File "tab1.py", line 10, in
alt.data_transformers.enable("data_server")
File "/opt/miniconda3/envs/group22env/lib/python3.8/site-packages/altair/utils/plugin_registry.py", line 177, in enable

Added altair_data_server to the yaml and it seems to have fixed it.
