+# A 3D surface plot allows you to visualize the data points in a terrain-like
+# surface in a 3D space powered by the WebGL engine. It is a variation of a
+# heatmap as they share the same data structure. The difference is that the
+# surface plot visualizes the heatmap values as the Z axis data, allowing you
+# to zoom in and out, and rotate to view the surface from different angles. Like
+# heatmap, nan values are also supported, resulting in empty
+# holes on the surface.
