Install sudo apt install ditaa
Description:

DiTAA is a small command-line utility that can convert diagrams drawn using ASCII art (“drawings” that contain characters that resemble lines, like | / and -), into proper bitmap graphics.

DiTAA also uses special markup syntax to increase the possibilities of shapes and symbols that can be rendered.
