I have a set of points in 2D generated by doing a DimensionReduce on a list of colors:



colors = RandomColor[100];
coords = DimensionReduce[colors, 2, Method -> "TSNE"];
ListPlot[Thread[Style[coords, colors, PointSize -> .05]]]


enter image description here



However, I would like to arrange these points into a regular 2D grid (or other lattice) while maintaining neighbourhoods as much as possible.



Is there a function to provide this transformation? Or am I better off writing something to shuffle the colors in a grid to minimise neighbor distances?

          It is hard to understand what you mean, but here is a simple take. Round can take an arbitrary step. That makes a grid of an arbitrary step.



          colors=RandomColor[100];
          coords=DimensionReduce[colors,2,Method->"TSNE"];

          gridStep=.5;

          ListPlot[
          Thread[Style[Round[coords,gridStep],colors]],
          PlotStyle->PointSize[.03],
          Frame->True,
          FrameTicks->Range[-10,10,gridStep],Range[-10,10,gridStep],
          GridLines->Range[-10,10,gridStep],Range[-10,10,gridStep],
          GridLinesStyle->Directive[Gray, Dashed]]
