Show HN: Kitcat 2.0 – A Matplotlib back end for terminal plotting

Kitcat 2.0 is a Matplotlib backend that enables plotting directly in the terminal, allowing users to generate and view charts without leaving the command line. The new version brings improvements over the original release.

Background

- Matplotlib is the most widely-used plotting library in Python, but it normally generates images for display in a GUI or saved as files like PNG/SVG. Kitcat is a "back end" that redirects Matplotlib's output to the terminal instead, rendering plots using text characters. - This lets you view graphs without leaving the command line, which is convenient for working on remote servers (e.g., over SSH) or in environments without a graphical display. The 2.0 version likely adds improved rendering, more plot types, or better performance. - The "Show HN" prefix means this was posted on Hacker News as a project showcase — a common way for developers to share their work with a technical audience.
