This node will visualize the given data as an interactive heatmap. The selected weight column defines the "heat" of each data point which is visualized on a world map.
The geometric elements are drawn in the order they appear in the input table. For example, if you want to show points within a polygon you want to have the points drawn last on top of the polygon. To do so sort the input table to have polygons as first rows followed by the points.
Please make sure the input table does not contain any rows with missing values.

Select the geometry column to visualize.
Select the color map to use for the heatmap. See branca for more information.
Select the weight column to visualize.
The minimum opacity the lowest value in the heatmap will have.
Zoom level where the points reach maximum intensity (as intensity scales with zoom), equals maxZoom of the map by default.
Radius of each datapoint of the heatmap.
The blur factor that will be applied to all data points. The higher the blur factor is, the smoother the gradients will be.
Base map setting for the visualization.
Select the base map to use for the visualization. If choose
Don't show base map, the base map will be hidden.
The default base map is
See Folium base maps.
Group of settings that define if a color legend is shown on the map and if so how it should be formatted. The color legend is only shown if you have selected a color column.
If checked, the color legend will be shown in the plot.
Set the caption for the color legend. By default, the caption is the name of the selected color column or empty for heat map.
