This probably needs to be documented better, but you now need to make sure you load Colors.jl manually (via using Colors) to get access to the show_plan implementation.

Now that #468 is merged, we have Dagger.show_logs and Dagger.render_logs - see the documentation (https://juliaparallel.org/Dagger.jl/dev/logging-visualization/#Logs-Visualization) for how to use these.
