[Feature] Local/custom viz

[niconoe]

Hello,

For a current project, I'd like to have the feature of adding custom/local visualizations to Caravel. That issue has been discussed in #697, which is closed now.

I therefore plan to start exploring how I could make this improvement, but have a few questions:

• Is it still something the team is interested in with a good chance of eventually merging my branch (if works properly)?
• Do you know if someone else is already working on this?
• Any strong opinions about what I should and shouldn't do?

Thanks a lot!

I would love to have a seamless and effordless way of putting new vizualisations in or take unused out. Every visualisation could be encapsulated as a module/class/... with a defined structure (interface) that can be extended. it would require a vizualisation-manager to find all currently installed viz and make them renderable for the slices and dashboard...

Thanks !

My idea is to make it work with "one directory per visualization". A first step would be to rework the existing stock viz like that, then in a second step to also load local stuff from a user directory. In that form, I don't think it would allow disabling existing viz like you suggest, but maybe we should go iteratively.

yes, splitting the viz into separate modules is the first step. abstracting the viz to conform to a common interface the second. a viz-manager or viz-factory can than be used through out the rest of caravel to get an instance of a named viz. a manager needs to know howto find a named viz and get a "instance" of it or delegate a call to it. definitely the last step in the journey...

FYI disabling visualizations is already possible https://github.com/airbnb/caravel/blob/master/caravel/viz.py#L2031

You can just override this in array in your caravel_config.py

Closing this due to being very old issue. The recent work on #5680 and #5692 reflect similar ideas.
