Ah, thanks for reporting this! This definitely looks like a bug. Can you open an issue? We introduced a new D3 backend but I forgot to integrate it with the report functionality

thanks! we'll work on it. in the meantime, if you want to generate the plot, you can use
ploomber plot
, and for the summary table
ploomber status

alright, you can downgrade to ploomber 0.18.1,
ploomber report
should work there. any feedback on the report? (things we should include, remove, change)

Copy code

you can change to use pygraphviz with
ploomber plot --backend pygraphviz

it's probably because you don't have graphviz, which is not pip-installable. check this out https://docs.ploomber.io/en/latest/user-guide/faq_index.html#conda-simplest
graphviz is required to make _py_graphviz work 😅
