cell density scRNAseq

Question

[pingu77]

Hello,

I am new to scRNAseq data analysis. I am trying to understand the meaning of plotting cell density (contour plot). For example, the package scDataviz can plot/reveal the regions with high cell density but how should I interprete the results? what is the biological implication of seeing an higher cell density in a particular cluster? What does it mean cell density?

Thank you in advance for your help!
