Is there a text-based tool to create a timeline diagram?

I searched for "timeline latex", and the screenshots of one of the results looks pretty nice: https://pypi.org/project/labella.

The first paragraph of the description:

>Labella.py is a Python 3 clone of labella.js that supports all the features of labella.js and addionally can generate TikZ PDF images for use in LaTeX.

You may check out Pikchr https://pikchr.org tool/language, inspired by the PIC language.

It's by the creator of SQLite and Fossil SCM. In fact the Pikchr functionality is bundled into Fossil SCM, and is directly supported in Fossil's UI (can be mixed in Markdown in the docs/wiki/forum).

The Pikchr language takes some patience to learn, but there're some useful examples to get you started. Plus, you could ask for help on the Forum.

Matplotlib: https://matplotlib.org/stable/gallery/lines_bars_and_markers...

Last time I had to embed diagrams I used mermaid js https://mermaid-js.github.io/mermaid/#/ which is made to be rendered alongside markdown. Not sure if your particular diagram is supported but the project has a big community around it so there should be a way.

timevis in R (https://www.rdocumentation.org/packages/timevis/versions/1.0...)

https://playground.diagram.codes has timelines, flow charts, etc. all live updated from text.
