circular heatmap

Introduction
Expression values are represented by colors, and clustered by distance. R package: circlize (Gu, Z. circlize implements and enhances circular visualization in R).
Data instructions
Input data are matrix format. The first row is sample names. Other rows are data lines (such as gene expression values). Only cluster genes, no scale.
Paper example
Gu, Z. circlize implements and enhances circular visualization in R Fig 1.
