ASCII Art Data Visualization in the Terminal like it's still 1970

This cookbook demonstrates how to generate ASCII art data visualizations directly in the terminal using the Xan library, recreating a vintage 1970s-style command-line graphics experience.

Background

- XAN is an open-source command-line tool for exploring and analyzing network data (graphs). It runs inside the terminal and has no graphical user interface. - This cookbook page shows how to turn those networks into charts and plots drawn with ASCII characters — lines, bars, and shapes made from text symbols — so they display in any terminal window. - The technique echoes 1970s teletype/line-printer output, before screens could show graphics. Modern data scientists often use Python's matplotlib instead. - Why it matters: for quick checks on a remote server or over an SSH connection, ASCII plots work without a graphical desktop, browser, or any visualization library installed.
