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.

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

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).
