ADDS ALTAIR PLOT COMPONENT AND SOME OTHER FIXES

[nissu99]

#2435

• - rename make_space_altair to something like make_altair_space_component
• - add make_altair_plot_component
• - Add support for all spaces. This means including the hexgrid and network transformation of the x and y coordinates.
• - Have a generic get_agent_data method

@quaquel @EwoutH I’ve added a new component, make_altair_plot_component. Could you kindly check if it aligns well with the project?

P.S working on space support.

Thanks for the PR! A few of the automated checks broke, could you look into what caused that?

I will leave the review to others.

@nissu99 also please look at #2643 and #2641 As you are @sanika-n are working in the same space

As it looks like you two are looking over the entire altair implementation I would also recommend looking at #2642 discussion

It is always good to collaborate and think together you may address some larger visualization challenges.

@tpike3 When I run the tests locally, they don't fail, but they are failing here.

I am not sure why your tests are passing locally, however for tests to pass they need to updated. It is expecting None and now getting Chart, because you added post process.

Thank You, the issue got resolved by adding altair to the toml file.

@quaquel @tpike3 i was making a generic get_agent_data function ,should i remove all the old functions like _get_agent_data_new_discrete_space or keeping them will be right?

[quaquel]

Removing stuff that has become redundant is fine.
