Marsilea: Declarative creation of composable visualization#

Marsilea is a Python library for creating composable visualizations in a declarative way. It is built on top of Matplotlib and provides a high-level API for you to puzzle different visualizations together like our logo. Complex annotated heatmaps, oncoprints, UpSet plots, sequence logos, genome tracks and single-cell panels are all the same few calls.
