# Brok UI block: Map Heatmap (`maps-heatmap`)

Geographic density heatmap of seismic activity around the Pacific Ring of Fire.

Brok UI is a Laravel Blade registry. `ui:add` copies this block into the app as plain Blade the app owns; it composes installed `<brok:*>` primitives and semantic design tokens.

## Install

```bash
php artisan ui:add blocks/maps-heatmap
```

## Render it

```blade
<x-blocks.maps-heatmap />
```

## Props

- `heading` (string, default `Seismic activity`) — Card title.
- `subheading` (string, default `Earthquake density, last 30 days`) — Supporting copy under the heading.
- `center` (array, default `[150, 0]`) — [longitude, latitude] the globe is initially centred on.
- `zoom` (float, default `1.3`) — Initial zoom level.
- `ramp` (array, default `['info', 'primary', 'warning', 'destructive']`) — Low-to-high heatmap colour ramp as token names, never raw hex.
- `quakes` (mixed|null, default `null`) — Optional GeoJSON FeatureCollection of Point features with a numeric properties.mag weight; null uses a sample Ring-of-Fire dataset.

## Use when

- Visualising geographic point-density data, such as seismic events, as a heatmap layer on a rotating globe.
- Showing a low-to-high legend alongside an event-count badge instead of discrete markers.

## Avoid when

- Needing discrete hub or courier markers with popups instead of a diffuse density layer; use maps-analytics, maps-logistics, or maps-delivery-tracker.

## Rules

- Render the installed block with `<x-blocks.maps-heatmap />` and pass data through its props; edit the copied file only for structural changes.
- Keep the semantic design tokens (`bg-background`, `text-muted-foreground`); never swap in raw colour utilities.
- Keep the `data-slot` attributes and the logical (start/end) spacing so the markup still mirrors under `dir="rtl"`.

Guidance

Use when

Visualising geographic point-density data, such as seismic events, as a heatmap layer on a rotating globe.
Showing a low-to-high legend alongside an event-count badge instead of discrete markers.

Avoid when

Needing discrete hub or courier markers with popups instead of a diffuse density layer; use maps-analytics, maps-logistics, or maps-delivery-tracker.

Anti-patterns

Do not replace semantic props with conflicting utility classes.
Do not remove labels, focus styles, or state attributes.

Usage

Render the block as a component, passing data where useful:

resources/views/welcome.blade.php Blade

<x-blocks.maps-heatmap />

Built from primitives

Composes <brok:*> Semantic tokens Re-themeable RTL-ready

This block composes installed <brok:*> primitives and semantic design tokens only — it does not reimplement any primitive. Re-theme it (light, dark, admin, customer) by editing CSS variables; flip the preview to RTL to confirm it mirrors.
