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.
