108-125: Consider simplifying the conditional logic.The method works correctly, but the conditional structure could be simplified by removing
elifafterreturnstatements.def _get_space_drawer(self): """Get appropriate space drawer based on space type.""" if isinstance(self.space, OrthogonalGrid): return OrthogonalSpaceDrawer(self.space) - elif isinstance(self.space, HexGrid): + if isinstance(self.space, HexGrid): return HexSpaceDrawer(self.space) - elif isinstance(self.space, ContinuousSpace): + if isinstance(self.space, ContinuousSpace): return ContinuousSpaceDrawer(self.space) - elif isinstance(self.space, VoronoiGrid): + if isinstance(self.space, VoronoiGrid): return VoronoiSpaceDrawer(self.space) - elif isinstance(self.space, Network): + if isinstance(self.space, Network): return NetworkSpaceDrawer(self.space) - else: - raise ValueError( - f"Unsupported space type: {type(self.space).__name__}.

228-228: Fix type annotation.Use the proper
Anytype from the typing module instead of lowercaseany.- dependencies: list[any] | None = None, + dependencies: list[Any] | None = None,You'll also need to import
Anyfrom typing:from typing import TYPE_CHECKING, Literal +from typing import TYPE_CHECKING, Literal, Any
240-240: Simplify space assignment logic.The current logic can be simplified using a more direct approach.
- renderer.space = getattr(model, "grid", None) or getattr(model, "space", None) + renderer.space = getattr(model, "grid", getattr(model, "space", None))
276-317: Consider refactoring complex Altair rendering logic.The Altair backend logic is quite complex and could benefit from being broken down into smaller helper methods for better maintainability and testing.
Consider extracting helper methods like:
_build_spatial_charts_list()_combine_charts_with_colorbar()_create_final_chart()This would improve readability and make the component easier to test and maintain.

🔇 Additional comments (9)
mesa/visualization/__init__.py (1)
16-16: LGTM!The changes properly expose the new
SpaceRendererclass as part of the public API.Also applies to: 24-24
mesa/visualization/space_renderer.py (1)
813-819: Verify the data indexing consistency between matplotlib and altair implementations.The data preparation for Altair uses different indexing compared to the matplotlib version. In matplotlib (line 688), the data is transposed with
data.T, while here the DataFrame is created with x as the first dimension.Ensure this difference is intentional and that both backends produce the same visual output for property layers.
mesa/visualization/solara_viz.py (7)
34-34: Import added correctly.The altair import is appropriately added to support the new Altair backend functionality in SpaceRendererComponent.
43-43: SpaceRenderer integration looks good.The import and parameter addition are correctly implemented. The documentation is appropriately updated to reflect the new required renderer parameter.
Also applies to: 57-57, 80-80
137-140: Good defensive programming with component list copying.Creating a copy of the components list before modification prevents unintended side effects on the original list. The space component integration is cleanly implemented.
179-179: Renderer parameter correctly passed to controllers.Both ModelController and SimulatorController properly receive the renderer parameter for consistent state management.
Also applies to: 189-189
202-204: CommandConsole handling updated consistently.The logic correctly checks and removes CommandConsole from
display_componentsinstead of the originalcomponentslist, maintaining consistency with the new component handling approach.
213-221: Clean component factory function.The
create_space_componentfunction provides a clean way to create space visualization components using closures. The implementation is simple and effective.
456-458: Model reset renderer updates implemented correctly.Both ModelController and SimulatorController properly update the renderer's space attribute when models are reset. The fallback logic using
getattrhandles both grid and space attributes appropriately.Also applies to: 583-585

@tpike3, thanks for checking. Missing out these little things is what I was afraid of.
|
@Sahil-Chhoker Thanks --- for #2 we need to keep it backwards compatible. There may be a couple ways to do this, but off the top of my head, can you use renderer to override the lack of components? |
|
@Sahil-Chhoker running through some more variants -
I pretty sure you have said this, but you need to update the Altair plot. Both backends should produce the same look and feel Right now
Also for the boltzmann wealth model altair is just showing circles and has a legend for opacity but the circles are not filling in. Still some very good work |
@EwoutH, @Sahil-Chhoker and I talked about this on Thursday and I was pretty reluctant as I thought it was an impossible tradeoff, but having some time to think on this an look through the code some more in this context I can see the appeal and a possible way forward. Goal being get to ---- # Simple usage (returns appropriate subclass)
renderer = SpaceRenderer(model, backend="matplotlib")
# Advanced usage (direct class access)
from mesa.visualization.backends import MatplotlibSpaceRenderer
renderer = MatplotlibSpaceRenderer(model)@Sahil-Chhoker Looking through the code to do this my impression is that this could be accomplished by As you are ahead of schedule, take a look and let us know what you think. |
The solara resizing feature was never in our control, can't fix it.
Both backends have their own quirks, and adding code to align the visual look for both makes them less flexible, therefore I think they are better left natural.
Not all the functionalities of matplotlib can be added to altair, but this one seemed important so I added it.
Thanks. |
I'm sorry but this doesn't clear the picture to me, can you explain your approach to me more thoroughly. |
Just to emphasize, this is very approximate as I have not tried refactoring your code to truly assess the feasibility. Goal is that the current approach works and each backend can function if accessed directly. My thought is what if you take the However if I am understanding the code correctly, currently it is
This would be more like
Let me know if this makes sense, as well as your thoughts and concerns. |

You are asking me to break the

Hmmm ok.. well keep cleaning up its performance, and let me chew on this for a bit, longer. @EwoutH and @quaquel would you be able to make Thursday at 1830 CEST to discuss? |
|
I've also cleared up all the known irregularities, so this PR is good to go from my side, let me know if you find something concerning. |
|
I have an additional thought I want to note, but not blocking for this PR.
I don't think the switching backends should need to be seemless. You purposely pick one that fits your model and features. Not every backend will be optimal for everything - or even have to be able to do or render anything (for example, I'm perfectly fine with only having one backend that supports NetworkSpaces). If it looks like this it would be fine:
Everything that's common goes into a general SpaceRenderer, in the back-end specific subclasses we can support specific features of specific backends. But, I think this also could be done after this PR is merged, we can always create additional subclasses and support those. |
I like this way of thinking and I now think this is more practical. Thanks for the suggestion, I'll be sure to explore in this direction and see what I can come up with in the future. |

(I will leave the final call for review and merge to @tpike3) |

@tpike3, I've made all the necessary changes, please give them a check. If everything comes out fine then this PR can be merged. |
Summary
Introduces
SpaceRendererinto the Mesa visualization system, aiming to simplify and decouple the logic of drawing agents, grids, and property layers.Motive
Part of my GSOC commitment.
Implementation
This PR introduces 2 new files, named
space_renderer.pyandspace_drawers.py.space_renderer.py:SpaceRendererclass, the main backend for Solara to render the space, agents, and property layers.draw_structure(): Draws the grid structure of the space.draw_propertylayer(): Draws property layers onto the space.draw_agents(): Draws agents onto the space.render(): A comprehensive method to draw all components at once.space_drawers.py:OrthogonalSpaceDrawer: For standard grid spaces.HexSpaceDrawer: For hexagonal grid spaces.NetworkSpaceDrawer: For network-based spaces.ContinuousSpaceDrawer: For continuous spaces.VoronoiSpaceDrawer: For Voronoi diagram spaces.SpaceRendererto handle the specific drawing logic for each space structure as they contain the specific grid/space drawing logic.Usage Examples
Additional Context
Checkout the discussion in #2772.
Currently only contains the full coverage for matplotlib spaces, only Orthogonal spaces are available for altair (with property layers).
