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.
Examples from papers

Output

1) How to plot?
1, Prepare data
2, Open with excel, and change into the same format as the example
3, Copy and paste data into the input frame
4, Select parameters
5, Submit and download figure files

2) Why NO figure generated?
Script need strigent input format, please read the instructions and examples carefully.
