The Krona architecture. XML within an XHTML document is used to store chart data within a web page. XML tag nesting is used to describe the hierarchy, while attributes are used to store magnitude and other information about each node. Krona displays these attributes as HTML elements, allowing hyperlinks to supplemental pages for each node. These could be either pages created with the Krona chart, such as BLAST results, or existing web pages, such as NCBI taxonomy pages for the taxonomy IDs of the nodes. The Krona interface JavaScript is linked into the chart either via the Web or locally.
