How to draw the Figure 4. Coordinate embeddings preserve multimodality in the main paper

Hello author, I wonder how you painted the Figure 4. Coordinate embeddings preserve multimodality in the main paper. Cause even use the coordinate as the GP output, the GP posterior couldn't give out a two-modal result as in the figure4.

We did it by correlating the gp posterior with coordinate embeddings on the grid.

The posterior is unimodal in embedding space, but that space is able to express multimodality in the 2D coords, which is what we show :)

It makes sense! But how can I draw a picture like that, could you kindly tell me, cause is a powerful illustration. ;D
