GOfan provides an intuitive approach to visualize Gene Ontology (GO) enrichment results. By converting complex GO DAGs into clean, circular representations, it allows researchers to quickly grasp the hierarchical structure and biological significance of enriched terms. The interactive and customizable visualizations facilitate exploration of key GO categories, enhancing interpretation and presentation of enrichment analyses.

1. Circular Visualization of GO DAGs – Converts complex GO hierarchies into clear, fan- or sunburst-shaped plots, making enrichment results easy to interpret.

2. Flexible Customization – Supports multiple data layers (e.g., q-values, gene ratios), color mapping, and saving in various formats via ggplot2.
