How to make a Dotplot like this in R for my clustered single cell data set

Question

[paria]

Hello all, I did my single cell analysis in Seurat. I would like to make a dot plot like the below one with dendrogram. Anybody knows how I can make this plot for my dataset. I would like it to visualize the expression of gene markers which I specify. This one is made using scanpy but I do work in R Seurat. I appreciate any help! Paria

Thank you! I am not sure how to create the scRNA_dotplot_data.tsv.gz needed for start of analysis. I appreciate it if you have done this and share the code with me. Paria
