chronos – TikZ-based package for drawing customisable timelines with support for colour schemes, styles and memoization

The package supports drawing timelines and aims to be highly customisable. Extensive configuration options are offered via a standard key-value interface based on pgfkeys. Custom colour schemes and styles are supported, and the package includes documented examples of each. Memoization works out-of-the-box if the memoize package is loaded.

The code was developed as a result of questions concerning difficulties in customising the output of existing packages for drawing timelines, which sometimes eschew pgfkeys and are often challenging to configure, even when based on PGF/TikZ.
