Quickstart (8 lines) Add a bar chart on top, labels on the left, a dendrogram on the right. Each side is just another building block. → Full tutorial Using scanpy/scverse? Marsilea has an official how-to in the scanpy documentation: Plotting with Marsilea Installation PyPI Conda Use with Claude Code Marsilea ships an official Claude Code skill: Once installed, the skill activates automatically whenever you ask Claude for a composable visualization. Marsilea itself still needs to be installed in your Python environment (see above). See the marsilea-skill repository, or Use Marsilea with AI assistants for other assistants and the machine-readable llms.txt. What is Composable Visualization? When we do visualization, we often need to combine multiple plots to show different aspects of the data. For example, we may need to create a heatmap to show the expression of genes in different cells, and then create a bar chart to show the expression of genes in different cell types. A visualization contains multiple plots is called a composable visualization. In Marsilea, we employ a declarative approach for user to create composable visualization incrementally.
