- Implemented support for customized pairs of cell type and gene list
- Added color control for nodes and edges
- Added cell type filtering functionality
- Integrated support for curved edges in visualization

**New Features**
- Added **`plotMarkerDotplot`** and **`plotMarkerDendrogram`** for enhanced marker gene visualization.
- Introduced support for **`batch_key`** to compute cosine similarities separately across different batches.
