`exp show`: Rename / Split to separate command the current `--html`

[daavoo]

My biggest question is whether this belongs in dvc exp show or might be better as a separate command, like dvc exp plot? A dvc exp plot command could also potentially show other things, like dvc plots diff between experiments, or checkpoint trends (like dvclive plots).

Why something as generic and conceptually disconnected as "HTML"? How about --parallel-coordinates-plot/--pcp? Or a separate command as @dberenbaum mentioned

To be honest --html for me would mean an HTML table, not plot. I would consider renaming this to be explicit about its meaning. I think --plot is a bit more explicit. But can limit us later if we decide to introduce more types of plots. Probably --pcp is the best unfortunately.

I think the best option would be to move to a separate command dvc exp plot with no flags for now. If more type of plots are added, we can introduce --pcp flags for whatever new type of plot.

It also opens possibility for further integration of plots and experiments

Yeah I can see why it was included to exp show initially, as it's basically the same info. But the presentation is completely different plus indeed maybe we want to add other plots later so I'd vote for a separate command.

One worry that I have is that adding a separate command, no matter the name, might create questions from the user's perspective.

If we name dvc exp plot/dvc exp report with the current features, users might ask where are the other plots (i.e. live plots) or why it's named report if it's only a PCP plot.

Proper exp plot/exp report requires mid-term engineering and product work in order to be implemented properly but the issue with the html name needs to be fixed short-term.

I'm wondering if just rename --html to --pcp for now until the features for separate command are consolidated 😅

--pcp is the option with the most implicit votes already and definitely an improvement so I believe we can go ahead with that for now indeed.

I don't think users would be confused about exp plot only having one plot though.

BTW where are live plots documented?
