cachai 0.1.3

Customizable visualization toolkit for science

---

---

Welcome! cachai (Custom Axes and CHarts Advanced Interface) is a fully customizable Python visualization toolkit designed to deliver polished, publication-ready plots built on top of Matplotlib. Currently, the package includes the ChordDiagram module as its primary feature. For details on the toolkit's capabilities, motivations and future projections, refer to this paper.

The code documentation is currently hosted in Read the Docs. To contribute or report bugs, please visit the issues page.

Fun fact:

"Cachai" (/kɑːˈtʃaɪ/) is a slang word from Chilean informal speech, similar to saying "ya know?" or "get it?" in English. Don't know how to pronounce it? Think of "kah-CHAI" (like "cut" + "chai" tea, with stress on "CHAI").
