PathVisio is a bioinformatics tool that lets you do everything with biological pathway diagrams. PathVisio helps you organize biological information and lets you present or publish that information easily. You can create and draw pathways, export them to many image formats, annotate them with links to online biological databases such as Ensembl, Entrez or HMDB, and add comments and literature references from pubmed. PathVisio also lets you sort through high-throughput experimental data in pathway context. This is a much more pleasant way to present data than just a large table. You can import microarray, proteomics or metabolomics data. PathVisio has a plugin interface that lets users customize it to new analysis types, new visualization methods, and new pathway formats. PathVisio is compatible with WikiPathways.
