HeatmapLayer
============

The `HeatmapLayer` class in `ipyopenlayers` allows you to visualize data using a heatmap. This layer type is particularly useful for displaying density or intensity of data points on a map. The heatmap layer can be customized with various properties such as blur, radius, and the list of data points.

Key Features
------------

- **Data Visualization**: Represents data points as a heatmap, where the intensity of color corresponds to the density or value of the data points.
- **Customizable Appearance**: Adjust the blur and radius of the heatmap to fine-tune its appearance.
- **Dynamic Updates**: Update the heatmap dynamically as the data points or styling properties change.

Example
-------

Below is an example of how to use the `HeatmapLayer` class to add a heatmap to your `ipyopenlayers` map:

.. jupyter-execute::

    from ipyopenlayers import Map, HeatmapLayer,RasterTileLayer

    # Create a map centered at coordinates [0, 0] with zoom level 0
    m = Map(center=[1.9700427801608893, 46.241720565969274], zoom=4)

    # Add layer
    layer=RasterTileLayer()
    m.add_layer(layer)

    # Define data points for the heatmap: [latitude, longitude, weight]
    data_points = [
    [42.3656, 9.1493, 16.79],  # Haute-Corse
    [43.4527, 6.2649, 16.28],  # Var

    [43.2998, -0.3674, 13.85],  # Pyrénées-Atlantiques
    ]

    # Create a HeatmapLayer with specified blur, radius, and data points
    heatmap_layer = HeatmapLayer(
        points=data_points,
        blur=20,
        radius=15
    )

    # Add the HeatmapLayer to the map
    m.add_layer(heatmap_layer)

    # Display the map
    m
