Looking for a diagram/graph renderer similar to graphviz/dot

I want to find a CLI text->png diagram renderer. It runs on Linux.

I have seen this software before, but I couldn't find it now. Maybe some of you know what the software is called?

## Example 1: https://envs.sh/Qfj.png

This diagram is created with something like ``` ellipse line ellipse ```

there is no concept of "edge/node" in this software.

## Example 2: https://envs.sh/Qfc.png

This diagram is created with something like ``` set direction to right ellipse set direction to down ellipse ```

This behavior is different from graphviz.
