Krona | Interactive metagenomic visualization in a Web browser

Allows hierarchical data to be explored with zoomable pie charts. Krona aims to answer questions regarding the relative abundance of taxa across multiple levels of the hierarchy simultaneously. The software supplements existing metagenomic visualizations by creating clearer depictions of abundance estimates and by enabling in-depth understanding of the underlying classifications. Windows and Mac users can create Krona charts with Microsoft Excel using Krona Excel template.
