I have a set of unstructured data (downloadable from https://drive.google.com/file/d/1BF3uq4uOlAmk-ybkpjSyYH7FuI0X5RkH/view?usp=sharing). When attempting to plot them, I get a rough "spiky" result.

ListPlot3D[data, Mesh -> None]

enter image description here

Is there any way to smoothen the plotted surface? Thank you all!

GradientFittedMesh[data, PerformanceGoal -> "Quality"]
ReconstructionMesh[data, Method -> Automatic]
ListSurfacePlot3D[data, MaxPlotPoints -> 8, Mesh -> None, 
 Axes -> False, Boxed -> False]
