# show_map { #brdr.viz.show_map }

```python
viz.show_map(aligner_results, dict_thematic, dict_reference)
```

Display a grid of maps showing alignment results across different distances.

This function creates a multi-panel figure where each subplot represents
the geographic state of the thematic data after being aligned using a
specific 'relevant distance' parameter.

## Parameters {.doc-section .doc-section-parameters}

| Name            | Type           | Description                                                                | Default    |
|-----------------|----------------|----------------------------------------------------------------------------|------------|
| aligner_results | [dict](`dict`) | A nested dictionary structured as `{theme_id: {rel_dist: ProcessResult}}`. | _required_ |
| dict_thematic   | [dict](`dict`) | Dictionary containing the original thematic geometries.                    | _required_ |
| dict_reference  | [dict](`dict`) | Dictionary containing the reference geometries used for alignment.         | _required_ |

## Returns {.doc-section .doc-section-returns}

| Name   | Type   | Description                                              |
|--------|--------|----------------------------------------------------------|
|        | None   | The function generates and displays a Matplotlib figure. |

## Notes {.doc-section .doc-section-notes}

The function automatically calculates the required number of rows for
a two-column grid. It relies on the internal `_make_map` helper
function to render the individual spatial layers.
