circos plot help

Question

[Genomancer]

I'm trying to visualize the distribution of SNVs in different monkey species using Circos, similar to this example:

I plotted the SNV correctly, but can't make the circular grids, and the circos documentation covers the radial grids only. Additionally, how to add the labels (10FFU-CB661, 10FFUCB633, etc.) radially in the same way, just like in the photo example

Any guidance, example configuration files, or relevant documentation would be greatly appreciated!
